Hi,
I understand that momentum before and after annihilation must be conserved. However, why isn't it possible to have a net momentum not equal to zero before hand, (ex. an electron and a positron traveling head on, but at different velocities) and then just have a single photon travel in the direction of that net momentum after annihilation?
Any insight would be greatly appreciated. We just barely touched on annihilation in class, and this was bugging me.
Thanks
