Homework #7:

1. What is the maximum possible fractional energy loss from Compton scattering for initial photon energies of 0.1, 1, 10, and 100 MeV?

2. What is the threshold neutron energy to excite the second level of Pb-207? If a 1 MeV neutron excites this level, what is the energy range for possible particle energies after the collision?

3. What is the energy range for possible particle energies after an elastic collision of a 1 MeV neutron with Pb-207?
