Hi, i would like about the decay of positronium (a electron and a positron going around the center of mass) in 2 photons: if i suppose the positronium decays at the rest, what is the energy of photons?
I think that the energy of a photon is the same of mass of rest of electron, because the binding energy of positronium is very small with respect to mass of electron at the rest.
If i would like to not neglect the binding energy of positronium, what is the nergy of photon?
Thanks
