An Oxygen nucleus with A = 16 consists of an excited state 6.13 MeV above the ground state. It emits a gamma. The obtainable energy is the sum of the kinetic energy of the recoiling nucleus and the energy of gamma. Find out the energy of the gamma?
Determine how much are gamma energies shifted when the decaying nucleus is moving? Assume that the oxygen nucleus in the problem is moving with a kinetic energy of 3 MeV prior to it emits the gamma. Determine what range of gamma energies will be generated?
