Abstract

The relativistic (e,2e) experiments on high-Z atoms performed in the last years by the Tübingen group1,2 have stimulated theoreticians to provide an acceptable model to explain the ionization processes involved. The relativistic distorted wave Born approximation (rDWBA)3,4,5 seems the one which yields the best results and has produced data in qualitative, and in most cases quantitative, agreement with the absolute measurements1,2. In this contribution we study, theoretically, the relevance of Coulomb boundary conditions for (e,2e) processes on the K-shell of high-Z atoms. We consider several fully relativistic approximations and compare calculated triple differential cross sections (TDCSs) with the measurements1.
