Abstract
Experimental alpha- and deuteron-induced total L-shell X-ray production cross section ratios, R = σ α /4 σ d, in the incident energy range 0.20 to 0.45 MeV/u are presented for elements Ge, Br, Zr, Mo and Ag; absolute cross section values are presented for Zr, Mo and Ag. The experimental ratios are always larger than the theoretical ones; further, the ratios of the higher- Z elements are quite independent of the reduced velocity. This is analogous to the situation found in the K-shell for elements ranging from Ca to Cu in a similar projectile reduced velocity range. The experimental absolute deuteron cross section values are lower than the theoretical ones by 10–30%; there is agreement with theory within the estimated errors. The alpha results show that, in the present incident energy range, the theoretical values decrease faster with energy decrease than the experimental ones.
