?When an electron and positron collide at the SLAC facility, they each have 50.0-GeV
Chapter 11, Problem 74(choose chapter or problem)
When an electron and positron collide at the SLAC facility, they each have 50.0-GeV kinetic energies. What is the total collision energy available, taking into account the annihilation energy? Note that the annihilation energy is insignificant, because the electrons are highly relativistic.
