2. A 662 keV gamma ray from 137Cs decay is Compton scattered atan angle θ.
(a) What is the energy of the resulting gamma ray afterscattering at 90â—¦?
(b) What is the energy of the resulting gamma ray afterscattering at 180â—¦?
(c) What is the maximum amount of energy that the gamma ray candeposit in a single Compton scatter?
