Ion-surface interactions and analysis

The $L$-subshell specific electron impact ionization cross sections, near the ionization threshold ($15<E<40$ keV) of gold are calculated from the measured production cross sections in this collaborative work between an experimental and a theoretical group. Calculations are performed using the distorted wave Born approximation formalism, and the modified relativistic binary encounter Bethe model to understand the data. The observed agreements and discrepancies between the two theoretical formalisms considered and the experimental data are reported.
