# High energy e- e- scattering, ratio inelastic/elastic cross-sections?

 P: 1,361 If we were to scatter high energy (say E>>m_e) electrons off each other is there a hand wavy argument to come up with a rough estimate for the ratio of inelastic to elastic cross-sections? Would the dominate inelastic collision between two high energy electrons result in a single photon emitted? Thanks for any help!
