Angular Differential Cross Sections for Excitation of Atomic Hydrogen by 25-, 50-, and 100-keV Protons

Abstract

Angular differential cross sections for the process ${\mathrm{H}}^{+}+\mathrm{H}(1s)\ensuremath{\rightarrow}{\mathrm{H}}^{+}(\ensuremath{\theta})+\mathrm{H}(n=2)$ are presented for 25-, 50-, and 100-keV protons incident on atomic hydrogen. The experimental results are in fair agreement with Glauber-approximation calculations.
