Cross sections for $L_{2,3}$ Auger emission in 22- to 300-keV ${\mathrm{H}}^{+}$ + Ar collisions

Measurements of total and differential $L_{2,3}$ Auger cross sections for ${\mathrm{H}}^{+}$ + Ar collisions at 22 - 150 keV are presented. Additional values of these cross sections were calculated from data in earlier investigations by Volz and Rudd and by Crooks and Rudd up to 300 keV. Angular distributions are found to be isotropic. Over most of the energy range the total Auger cross sections are a factor of 2 smaller than predicted by Garcia's binary-encounter calculations.
