Calculate the proton separation energy for Neon.
A method of cancer treatment known as gamma knife radio-
therapy uses multiple beams of gamma rays to attack a tumor
while leaving nearby tissue relatively unaffected. The source of
gamma rays is radioactive cobalt, which reliably produces
photons with E
the
1.17 MeV. Suppose one of these photons
interacts with a valence electron in the tumor, which causes
the photon to scatter at an angle of o
initial direction of motion. What will be the photon's energy
E' after the scattering event (in the units MeV)? Draw a be-
fore/after diagram for the photon-electron collision, and make
sure that your sketch conveys the idea that momentum is con-
served. (Hint: if you plug the electron's mass into E
then you get mec = 0.511 MeV, which can be quite useful
when performing calculations. Also, review textbook section
27.5 if needed for this problem.)
