Compton Scattering: Special Cases
Recoil: q = 180†, cosq = -1KEeout = 2hna / (1 + 2a);hní = hn/(1 + 2a); max. energy to e-.
Minimum energy transfer to electron:q = 0†, cosq = 1, KEeout ª 0, hní = hn
Low-energy photon, a << 1:hní ªhn, KEeout ªhn a(1-cosq)
High-energy photon, a >> 1: hní ªhn / [a(1-cosq)], KEeout ª hn(minor significance)
