Before the discovery of the neutron, it was proposed that the penetrating radiation produced when beryllium was bombarded with a particles consisted of high-energy y rays (up to 50 MeV) produced in reactions such as x +Be-+"C + γ. (a) Calculate the Q value for this reaction. (b) If 5-MeV a particles are incident on 'Be, calculate the energy of the13C nucleus and, hence, determine the energy of γ radiation assuming it is emitted as a single photon.
