The e+e- pair production in relativistic ions collision and its correspondence to electron scattering
Abstract
It is shown that the processes of electron(positron) scattering and e+e- pair production in the Coulomb fields of two relativistic ions, can be expressed through the amplitudes of lepton scattering off the ion Coulomb field via Watson expansion. We obtained the compact expressions for these amplitudes valid in the high energy limit and discuss the crossing symmetry relations among the considered processes.
