A γ photon of momentum P is emitted by a radioactive nucleus of mass M . The total energy released in this process will be (Assume nuclei is free to recoil) [ c is the speed of light]

Question

A γ photon of momentum P is emitted by a radioactive nucleus of mass M . The total energy released in this process will be (Assume nuclei is free to recoil) [ c is the speed of light], Pc, P 2 2 M, P c + P 2 M, P c + P 4 M

MARKS App · Accepted Answer

The momentum of the atom due to recoil = P 2 2 M E = Pc + P 2 2 M
