An effective treatment for cancer takes advantage of the fact that boron readily captures slow neutrons. In the body, boron is much more likely to capture a neutron than are carbon, oxygen, or hydrogen. Because of the chemical similarity of boron and carbon, a rapidly dividing cellular structure like that of a tumor will take up boron that is delivered intravenously or by injection. When boron-10 captures a neutron nearly at rest, the resulting excited boron-11 nucleus decays rapidly, emitting an alpha particle and a gamma-ray photon. Most of the energy released is deposited very near the capture site. 

(a) Write out this nuclear reaction, specifying the daughter nucleus. 

(b) The photon has an energy of 0.48 MeV. What is the total kinetic energy of the alpha particle and daughter nucleus?
