High-energy $e^{+}{e}^{-}$ photoproduction in the field of a heavy atom accompanied by bremsstrahlung

P. A. Krachkov, R. N. Lee, A. I. Milstein

Helicity amplitudes and differential cross section of high-energy $e^{+}{e}^{-}$ photoproduction accompanied by bremsstrahlung in the electric field of a heavy atom are derived. The resu…
