Compton-scattering contribution to the double ionization of He in the [Formula Presented] approximation

We study the Compton-scattering contribution to the double ionization of helium within the [Formula Presented] approximation. We present results for the final-photon energy distribution for incoming photon energies of 6 and 20 keV using two alternative forms for the [Formula Presented] operator, nam...
