Abstract
Distorted-wave perturbation theory with special reference to CDW1 (Crothers and McCann (1983)) is used to calculate the absolute cross section for electron capture to the continuum. Results obtained for the impact of fast fully stripped ions of oxygen, carbon, helium and hydrogen upon helium atoms are compared with the measurements of Andersen et al. (1986). Theory and experiment are found to be in excellent accord for the cross section magnitudes, but are in disagreement for the cusp asymmetry parameter.Keywords
