Title: Excitation and charge transfer in p+H(2s) collisions

Abstract

Excitation and charge transfer cross sections for proton collisions with 2s excited state hydrogen are calculated using time-dependent lattice, atomic-orbital close-coupling with pseudostates, and classical trajectory Monte Carlo methods. The time-dependent lattice calculation yields {delta}n=1 excitation and {delta}n=0 and {delta}n=1 charge transfer cross sections at 5, 10, and 15 keV incident energy. The atomic-orbital close-coupling with pseudostates calculation yields excitation cross sections to n=3-5 and charge transfer cross sections to n=1-5 at a number of incident energies between 1 and 100 keV. The time-dependent lattice and close-coupling pseudostates calculations are found to be in good agreement with previous standard close-coupling results. The close-coupling with pseudostates calculations are used to benchmark the classical trajectory Monte Carlo calculations, which are widely used in astrophysical and laboratory plasma modelling.
