Abstract

The paper presents a new assessment of cross-section data for excitation of He (1 1S) by proton impact at energies higher than 10 keV (in a few cases 6 keV). Data for excitation to n 1L states of He (n less-than-or-equal-to 4, L = S, P and D) are given in tables. The data at high energy (approximately 1000 keV) are linked to the first Born approximation, and data at low energies are linked in some cases to the close coupling atomic orbital results of Fritsch, who also made a critical evaluation of the cross-sections for excitation of helium by protons.
