Formation of ions by high energy photons

Quantum Physics 2015-06-26 v1

Abstract

We calculate the electron energy spectrum of ionization by a high energy photon, accompanied by creation of electron-positron pair. The total cross section of the process is also obtained. The asymptotics of the cross section does not depend on the photon energies. At the photon energies exceeding a certain value ω0\omega_0 this appeares to to be the dominant mechanism of formation of the ions. The dependence of ω0\omega_0 on the value of nuclear charge is obtained. Our results are consistent with experimental data.
