Abstract

Relative L-subshell ionization cross sections have been measured using a series of ions at a fixed collision velocity in order to study the projectile nuclear charge dependence. Thin Sm, Er, and Au targets were bombarded by 2H+, 4He+, 12C+, and 14N+ ions MeV u impact energy. The cross sections were normalized to the data obtained by deuterons. The experimental results have been compared with calculations in the perturbed stationary state approximations with Coulomb deflection, binding and relativistic corrections included (CPSSR) as well as with the recent second order calculations. Particularly large discrepancies have been found for the L2 subshell comparing the CPSSR results with the measured values. These discrepancies have been reduced significantly by the inclusion of the second order effects.
