 P: 99 Hi, I'm considering the following process n+p→d+$\gamma$ where d is the deuteron and $\gamma$ a photon. I want to find out the energy of the photon. I know it will be much less than the rest mass of the deuteron (1875.666 MeV/c2). Can I simply use conservation of energy here? i.e E$\gamma$ = Ei - Ef? Thanks :)
 P: 99 So is it really as simple as E$\gamma$ = (En+Ep) - Ed?
