Accurate cross sections are being determined primarily for ionization in
p-He^+(1s, 2s, or 3s) collisions for proton energies from about 0.3 to 2
MeV using a coupled-Sturmian-pseudostate approach and also the first-Born
approximation.  These results are being compared with existing Born and
continuum-distorted-wave results.
