Abstract

Cross sections for K-shell ionization by charged particles have been calculated within the framework of the impact-parameter formalism using the distortion approximation. The continuum wave functions are represented by pseudostates. It is confirmed that the pseudostate wave function can well reproduce the shape of the continuum wave function for low-energy electrons. The calculated total K-shell ionization cross sections for a number of ion-atom collision systems are shown to be in good agreement with the experimental results. For protons on copper, the ionization probabilities as a function of impact parameter are also found to agree with the measured values. The present results indicate that the distortion approximation using pseudostates is very useful in the study of K-shell ionization cross sections over a large range of ion-atom collision systems.
