INTERMEDIATE conclusions PWIA describes data fairly well at low and moderate intrinsic momenta (up to 50-300 MeV/c PWIA + GEA describes data in te wole kinematical region in.e. ( = NN ig energy e.m. processes off 3 He PWIA + GEA wit factorization adeuately describes unpolarized spectator SIDIS ( = eff (t,q,x Bj at intrinsic momenta up to 400-500 MeV/c Since in te standard SIDIS processes one integrates over undetected removal energy and momenta (from 0 to infinity te PWIA + GEA ( = eff (t,q,x Bj wit factorization can be applied to extarct free Information information also from polarized SIDIS processes L.P.
