Hydrogen-atom excitation and ionization by proton impact in the 50- to 200-keV energy region

Abstract

We report results for $n=2\mathrm{}$ and $n=3\mathrm{}$ excitation and ionization in proton-hydrogen collisions. The calculations use a single-center (target) basis with $s$, $p$, and $d$ angular momentum states, and include all terms in the Born series. For projectile energies between 50 and 200 keV the results are in excellent agreement with recent experiments.
