Analytical calculation of Coulomb corrections to $e^{+}{e}^{-}$ pair production at intermediate photon energies

R. N. Lee, A. I. Milstein, V. M. Strakhovenko

First correction to the high-energy asymptotics of the total $e^{+}{e}^{-}$ photoproduction cross section in the electric field of a heavy atom is obtained with the exact account of this…
