摘要：

We have applied theoretical many-body techniques to analyze our experimental ionization-excitation cross sections for fast e-+He and H++He-collisions. By using the main first-order, second-order and interference cross terms we have derived an approximate value for the cross section ratio sigma+*(e-)/sigma+*(H+) for He+(2p) which is in good agreement with experiment.
