Description
Differential and integral cross sections for singlet-singlet (11S → n1S, n=2,3,4; 21S → m1S, m=3,4) and triplet-triplet(23S → 33S) excitations of the helium atom proton impact are calculated in the framework of the distorted-wave approximation. A comparative study is made by taking the distorted-wave (Coulomb-wave) approximation in either the initial or final channel or both. The energy range studied is from 100-500 keV. The computed results are compared with the plane-wave results and other available theoretical results. (author)
