Unformatted text preview: Physics 5110 Homework 7 (due Mar 3) March 2, 2010 Please note: the Midterm exam will take place Monday, March 8, in class. Open book, open notes, calculators needed. The exam will cover Chapters 1-7. 1. (30 pts) The reaction p + 7 3 Li + occurs in the sun. The mass defect of 7 Li is 0 . 01654 u . Find the Q value of the reaction. Suppose the proton and lithium encounter each other head-on with kinetic energies 2 MeV and 1 MeV, respectively. What range of energies (maximum and minimum) will the resulting alphas have in the laboratory frame? 2. (40 pts) The reaction 13 6 C(d,p) 14 6 C has a resonance when the incident deuteron has a laboratory energy of 2.45 MeV. (a) (10 pts) What is the excitation energy of this compound nucleus relative to the 15 7 N ground state? (You can get the ground state energy from the mass defect given in our favorite Chart of Nuclides site.) (b) (10 pts) Given that the reaction has a Q-value of 5.952 MeV, what is the maximum laboratory kinetic energy of the produced proton?is the maximum laboratory kinetic energy of the produced proton?...
