1 1 University of California, Berkeley Physics H7C Spring 2011 (Yury Kolomensky) THE FINAL EXAM Monday, May 9, 7 10pm Maximum score: 200 points NAME: SID #: You are given 180 minutes for this exam. You are allowed three sheets containing any information you wish on both sides. Derive all answers symbolically, then plug in the numbers, if appropriate. You may leave expressions such as 2, e, π unevaluated. Your description of the physics involved and symbolic answers are worth much more than the numerical answers. Show all work, and take particular care to explain what you are doing. Write directly on the exam, and if you need extra pages, make sure to put a note on the corresponding sheet. Cross out rather than erase parts of the problem you wish the grader to ignore. Box or circle final answers. There are six problems with points assigned as shown. Partial credit will be given for incomplete solutions, so attempt to do all problems. Some problems will take significantly longer than others, so judge time appropriately. At the beginning of the exam, please look through all problems and plan how you ll spend your time. If you need to ask a question, come to the proctor. Your question and the answer will be written on the board. Read all problems carefully. If you get stuck on a problem, move to another. Try to remain calm and work steadily. Good luck!

5 5 2. (35 points) A relativistic electron with energy E = 9.0 GeV collides head-on with a relativistic positron with energy E + = 3.1 GeV, traveling in the opposite direction to the electron. In the resulting annihilation, a particle Υ(4S) is created in a reaction e + e Υ(4S). Find the mass of Υ(4S) and its velocity in the LAB frame. 3. (45 points) An optical system consists of a thin converging lens with focal distance f = 50 cm, and a iris attached to the back of the lens. A screen is placed b = 75 cm behind the iris. The system is illuminated with plane light waves of wavelength λ = 0.5 µm. Find the possible values of the radius of the iris such that the intensity at the center of the screen is maximal. 4. (30 points) Neutron diffraction is one of the methods used to determine crystal structure of a material. Imagine that a beam on mono-energetic neutrons (of mass m and kinetic energy K) impinging on a crystal lattice with atomic spacing d at the inclination angle θ (it is customary in crystallography to measure the angle from the plane of the crystal, as opposed to the normal to the surface). If neutron energy is relatively small (thermal or cold neutrons), they would typically reflect off the nuclei of the crystal lattice elastically. (a) (20 pts) At what angles would the intensity of the reflected neutrons be maximal?
