Pair creation with bound electron for photon impact on bare heavy nuclei

In this paper we present numerical calculations for the process of bound-free electron-positron pair production following photon impact on bare nuclei. The calculations are based on exact Coulomb waves. We include total as well as differential cross sections for production of both K and L electrons for a wide range of photon energies and nuclear charge numbers. Significant deviations from lowest-order Born theory appear for moderate and high...
