Abstract

Tables of ab-initio total cross sections, probabilities at zero impact parameter, and impact parameter moments are presented concerning the ionization of Ne, Ar, Kr, and Xe by proton impact in the energy range (0.1-10) MeV. Calculations correspond to the continuum distorted wave eikonal initial state approximation (CDW-EIS) for energies up to 1MeV, and to the first Born approximation for larger energies. Results displayed in the tables are disaggregated for the different initial bound states, considering all shells for Ne and Ar, L-M-N shells of Kr and M-N-O shells of Xe. Our inner-shell ionization cross sections are compared with the available experimental data and with the ECPSSR results.
