The -deformed hyperbolic Rosen-Morse potential is perturbed by-deformed noncentral trigonometric Scarf potentials where all of them can be solved by using Asymptotic Iteration Method (AIM. This work is limited to spin symmetry case. The relativistic energy euation and orbital uantum number euation l D have been obtained using Asymptotic Iteration Method. The upper radial wave function euations and angular wave function euations are also obtained by using this method. The relativistic energy levels are numerically calculated using Matlab and the increase of radial uantum number n causes the increase of bound state relativistic energy level in both dimensions D=5and D=3.The bound state relativistic energy level decreases with increasing of both deformation parameter and orbital uantum number n l.. Introduction Dirac euation as relativistic wave euation was formulated by P. A. M Dirac in 98; the exact solution of Dirac euation for some uantum potentials plays a fundamental role in relativistic uantum mechanics []. In order to investigate nuclear shell model spin symmetry and pseudospin symmetry solutions of Dirac euations have been an important field of study in nuclear physics. The concept of spin symmetry and pseudospin symmetry limit with nuclear shell model has been used widely in explaining a number of phenomena in nuclear physics and related field []. In nuclear physics spin symmetry and pseudospin symmetry concepts have been used to study the aspect of deformed and super deformation nuclei.theconceptofspinsymmetryhasbeenappliedtothe level of meson and antinucleon [3]. Pseudospin symmetry has been observed in deformed nuclei and can be enhanced in heavy proton-rich nuclei [4]. Solutions of Dirac euation for some potentials under limit case of spin symmetry and pseudospin symmetry have been investigated intensively whether in three- [5 6] two- or one- [7 3] dimensional space some D-dimensional spherical symmetric spacetimes [4 5]. However The D-dimensional Dirac euation with (D -dimensional separable noncentral potential has not been investigated yet; therefore it may be worthy to investigate Dirac euation in 5 dimensions with separable 4-dimensional noncentral potential in this study. In recent years some researchers have studied solution of Dirac euation with uantum potentials with different application and methods. These investigations include Eckart potential and trigonometric Manning-Rosen potential

Asymptotic Iteration Methods (AIM have small deviation for determination of eigenenergies and eigenfunctions of Dirac euation. The separable D-dimensional uantum potentials are not studied yet by some researchers. In this paper we use Asymptotic Iteration Method (AIM to solve the Dirac euation under influence of separable D-dimensional uantum potentials. The relativistic energy levels can be obtained from calculation of relativistic energy euation using Matlab R3a. In Section we present basic theory of Dirac euation in hyperspherical coordinate with Ddimensional separable uantum potential. In this section deformed uantum potential is also included which is proposed by Dutra in 5 [9]. In Section 3 we present Asymptotic Iteration Method. Result and discussion are included in Section 4 and in Section 5 we present the special case in 3- dimensional space. In the last section we present conclusion.. Dirac Euation with Separable -Deformed Quantum Potential in the Hyperspherical Coordinates For single particle Dirac euation with vector potential V(r and scalar potential S(r in the hyperspherical coordinate can be expressed as follows (in the unit h=c= [3 4]: { α p+ β(m+s( r}ψ( r ={E V( r}ψ( r where p EandM are D-dimensional momentum operator total relativistic energy and relativistic mass of the particle respectively: ( α i =( σ i ( σ i β =( (3 where σ i are Pauli s matrices and is the unit matrix. Here we use relations between Pauli s matrices as σ i σ j + σ j σ i =δ ij. (4 The wave function of Dirac spinor can be classified in two forms upper spinor χ( rand lower spinor φ( ras follows [5 6]: ψ( r=( χ( r φ( r F nk (r r (D / Yl l...l D ( x =θ θ...θ D (5 =( i G. nk (r r (D / Y l l ( x =θ... l D θ...θ D By substituting ( (3 and (5 into ( we get σ pφ ( r = (M E+(V ( r +S( r χ ( r (6 σ pχ ( r = (M+E (V ( r S( r φ ( r. Exact spin symmetry limit is characterized with V( r = S( rbutforspinsymmetrylimitv(r S(r = Δ which is constant and for pseudospin symmetry limit V(r + S(r = Σ which is also constant. For spin symmetry limit we have dδ( r /dr = since Δ( r = C s = constant; therefore (6 can be rewritten as σ pφ ( r = {(M E +Σ( r} χ ( r (7 φ ( r = σ p (M + E C s χ ( If (8 is substituted into (7 we get p χ ( r r. (8 ={(M+E C s } [ {(M E + (Σ ( r}] χ ( r where ( σ p ( σ p = p. ( Using momentum operator definition in uantum mechanics where p = i D the hyperspherical Laplacian D is given as [5] D = r D r (rd r +(L D r. ( The eigenvalue of L D is l D (l D +D and the angular momentum operator is expressed as [5] L D = { sin D (sin D θ θ D θ D D θ D ( L D sin }. θ D (9

The effective potential can be written as V Σ (r =[{ cosh (αr +V tanh (αr} + r { V(θ sin θ sin θ 3 sin θ V(θ 3 sin θ 4 +V(θ 4 }] with angular potentials V(θ i taken as V(θ = b +a (a sin θ V (θ = b +a (a sin θ V (θ 3 = b 3 +a 3 (a 3 sin θ 3 V (θ 4 = b 4 +a 4 (a 4 sin θ 4 V(θ sin θ 3 sin θ 4 (4 b (a /cos θ sin θ (5 b (a /cos θ sin θ (6 b 3 (a 3 /cos θ 3 sin θ (7 3 b 4 (a 4 /cos θ 4 sin θ. (8 4 By substituting (4 into (3 and using variable separation method we get the radial part and the angular part of Dirac euations in hyperspherical coordinate with D=5... The Radial Part. The D-dimensional Dirac euation with -deformed hyperbolic Rosen-Morse potential plus deformed trigonometric Scarf noncentral potentials can be resolved into the form of radial part and angular part euations. The radial part of D-dimensional Dirac euation in this case can be expressed as d F nk (r dr (l D + (D / (l D + (D 3/ r F nk (r V +[{ cosh (αr V tanh (αr} {M+E} {M+E C s } {M E}]F nk (r = with λ 4 =λ D =l D (l D +D.

( ( (3 Euations ( (3 are the angular part of Dirac euation for θ until θ 4 respectively.thed-dimensional relativistic wave functions and orbital uantum numbers are obtained from those euations. 3. Review of Asymptotic Iteration Method (AIM Asymptotic Iteration Method (AIM is an alternative method which has accuracy and high efficiency to determine eigenenergies and eigenfunctions for analytically solvable hyperbolic-like potential. Asymptotic Iteration Method is also giving solution for exactly solvable problem [7]. AIM is used to solve the second-order homogeneous linear euation as follows [5 3]: y n (x =λ (x y n (x +S (x y n (x (4 where λ (x =and prime symbol refers to derivation along x. Theotherparametern is interpreted as radial uantum number. Variables λ (x and S (x are variables that can be differentiated along x.togetthesolutionof(4wehaveto differentiate (4 along xandthenweget where y n (x =λ (x y n (x +S (x y n (x (5 λ (x =λ (x +S (x +λ (x S (x =S (x +S (x λ (x.

Eigenvalue can be found using euation given as Δ k (z =λ k (z s k (z λ k (z s k (z = (3 where k = 3... is the iteration number and n r is representation of radial uantum number. Euation ( is the second-order homogeneous linear euation which can be solved by comparing it with the second-order linear euation as follows []: where y (z =( azn+ t+ bzn+ z y (z wz N y (z bzn+ (σ n = Γ (σ+n Γ (σ σ= t+n+3 N+ ρ= (t + b+a.

(34 The -deformed hyperbolic and trigonometric functions are used as one of the parameters in the modified Rosen- Morse potential and noncentral Scarf trigonometric potentials were defined by Arai [4] some years ago as follows: sinh αr = eαr e αr (35a cosh αr = eαr +e αr (35b tanh αr = sinh αr cosh αr cosh αr sinh αr =. (35d (35c Deformation with-parameter in the hyperbolic function can be extended into trigonometric function. Definition of trigonometric function can be arranged by the same way as in the hyperbolic function introduced by Suparmi et al. [7] as follows: sin ar = eiar e iar cos ar = eiar +e iar cos ar + sin ar = tan ar = sin ar cos ar sec ar = cos ar d sin ar =acos dr ar d cos ar = asin dr ar d tan ar =asec dr ar. (36 By a convenient translation of spatial variable one can transform the deformed potentials into the form of nondeformed potentials or vice-versa. In analogy to the translation of spatial variable for hyperbolic function introduced by Dutra [9] we propose the translation of spatial variable for hyperbolic and trigonometric function as follows: r r+ ln α r r ln α r r+ ln iα r r ln iα. And then by inserting ( into (8 and (9 we have sinh αr sinh αr; cosh αr cosh αr; sin αr sin αr; cos αr cos αr.

(39 Euation (39 cannot be solved directly when l D = ; in this condition we use approximation to solve centrifugal term with Pekeris approximation. Because we have used deformed uantum potential the Pekeris approximation in this condition can be expressed as [3] r = e αr re (c +c +e αr +c ( e αr +e αr (4 with c = ( +exp ( αr e 8αr ( e αr e +exp ( αr e (4a (3+αr e c = (exp (αr e +(3( +exp ( αr e αr e (3+αr e ( +exp ( αr e αr e c =(exp (αr e + ( +exp ( αr e (3 αr e +αr e 4αr e +exp ( αr e.

(74 (75 (76 (77 (78 (79 The unnormalized angular wave functions for θ θ 3 and θ 4 are in the same pattern as the angular wave function for θ so we obtain the last three angular wave functions by simple change of parameters in (7 with parameters in (74 (79. The relativistic energy levels are calculated numerically using Matlab program R3a. Table shows the relativistic energy levels as a function of deformation parameter ; the relativistic energy E decreases when deformation parameter increases. Here we apply the value of from. until.withstep..therelativisticenergylevelsasafunction of orbital uantum numbers n l are also shown in Table. The magnitude of energies E decreases when the orbital uantum numbers n l increase. The relativistic energy levels as a function of radial uantum number n are shown in Table. The relativistic energies E increase when radial uantum number n increases. The relativistic energies numerically also change as a function of potential parameters a i and b i where i = 3 4 are the components of ith noncentral potential (Table 3. The relativistic energies E increase when both potential parameters in each potential component increase. This suggests that the bounded energies become less bounded with increasing of potential parameters. The unnormalizedangularwavefunctionsarelistedintable4. The unnormalized radial wave functions are plotted by using (46 and (59 as shown in Figure. From Figures (a (c it is seen that the amplitude of the wave function increases when the orbital uantum number increases. This suggests that the probability of finding particles is larger for higher orbital uantum number n l. 5. Special Case for Three-Dimensional System In three-dimensional case D=3the bound state relativistic energy levels are calculated numerically from (58 (43 (44 (56 (69 (74 and (77 using Matlab software R3a and are presented in Tables 5 6 and 7. By using (44 and (6 the unnormalized radial wave functions are listed in Table 8. In Table 5 the relativistic energy levels decrease

From Table 7 we can conclude that the value of relativistic energies increases with the increase of the radial uantum number n and with either the presence or absence of angular potential parameter. The angular potential parameters a and b influence the relativistic energy level where the relativistic energy levels increase by increasing the angular potential parameter. The unnormalized upper radial wave functions are listed in Table 8 when the radial uantum numbers are n = and n = and C is the normalization constant. The unnormalized angular wave functions as functions of θ and θ are listed in Table 9. Without the presence of the noncentral potential degeneracy energy spectra occur in the spin doublets with uantum numbers (nlj = l+/ and (nlj = l / where n l andj are the radial the orbital and the total angular momentum uantum numbers respectively for example (np / np 3/ forl = but for difference values of j=/and 3/ (nd 3/ nd 5/ forl= with (j =3/and 5/ (nf 5/ nf 7/ forl=3with (j =5/ and 7/and(ng 7/ ng 9/ forl=4with (j =7/and 9/. The degeneracy energies can be removed with the presence of noncentral potential by changing l K where K= l and K=lfor K<and K>. 6. Conclusion In this study we have obtained the bound state solution of the 5-dimensional Dirac euation with separable -deformed uantum potential under condition of spin symmetry. The upper component of Dirac spinors and relativistic energy have been obtained using Asymptotic Iteration Method (AIM. The numerical result shows that the bound state relativistic energy level for spin symmetry case with both dimensions D=5and D=3increases with increasing of radial uantum number n and decreases with increasing of both deformation parameter and orbital uantum number n l. The degeneracy energy states occur in the absence of deformed noncentral potential. Competing Interests The authors declare that they have no competing interests.
