Doubly Differential Electron-Emission Spectra in Single and Multiple Ionization of Noble-Gas Atoms by Fast Highly-Charged-Ion Impact
Physical Review A. Atomic, Molecular, and Optical Physics
Abstract
Low-energy electron emission spectra are studied in collisions of 3.6 MeV/amu Au53+ ions with neon and argon atoms for well-defined degrees of target ionization. We calculate doubly differential cross sections as functions of the recoil-ion charge state in the continuum-distorted-wave with eikonal initial-state approximation using a binomial analysis of the total and differential ionization probabilities, and compare them with the present and with previously published experimental data. Very good agreement is found for the single-ionization spectra and for double ionization of neon, while some discrepancies are observed in the spectra for double and triple ionization of argon.
