Abstract

The continuum-distorted-wave-eikonal-initial-state (CDW-EIS) model was used to study multiple electron emission from argon due to proton impact. The independent electron approximation was used to obtain the multiple ionization cross sections. The Hartee-Fock-Slater potentials were used within the CDW-EIS model to compare the doubly differential cross section (DDCS) with experimental results. The target bound and continuum wavefunctions were obtained by solving the time-dependent Schrodinger equation for the target Hamiltonians. The analysis suggested that the contribution of multiple ionization from Auger cascades to the K-shell was negligible.
