if a 2.000Å (.2nm) photon interacts with the bound electron in an hydrogen atom (binding energy 13.6 eV) with a Compton collision. The electron moves forward in the same direction as the incident photon. It may be convenient to use hc 12408eV Å
a) What is the kinetic energy of the electron?
b) What is the energy of the scattered photon?
c) Why is the total energy of the scattered photon and scattered electron equal to the incident photon energy? (I.e. at what point(s) was the 13.6 eV binding energy ignored?)
