Differential and integral cross sections for singlet-singlet (11S to n1S, n=2, 3, 4; 21S to m1S, m=3, 4) and triplet-triplet (23S to 33S) excitations of the helium atom by 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.
