Abstract:

The distortion approximation is applied to some excitation processes of He cross-sections being obtained for incident proton energies in the range 10 keV to 1,000 keV and for incident alpha particle energies in the range 40 keV to 4,000 keV. For proton impact the maxima crosssections are found to be 0.18 and 0.035, at 88 keV and 124 keV respectively and for alpha particle impact they are found to be 0.61 and 0.101 at 511 keV and 935 keV respectively.
