Abstract:
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, named in the literature as the length and velocity forms. It is shown that, although there is a form dependence of the results, these differences tend to cancel at the level of the total cross section as the incoming photon energy increases. Our results support the conclusion that the asymptotic limit for the ratio of double-to-single ionization by Compton scattering is about 0.8%. © 1996 The American Physical Society.
