Abstract

Relative L-subshell ionization cross sections were 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** plus , **4He** plus , **1**2C** plus , and **1**4N** plus ions at 0. 2 Mev/u impact energy. The cross sections were normalized to the data obtained by deuterons. The experimental results were 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 were found for the L//2 subshell comparing the CPSSR results with the measured values. These discrepancies were reduced significantly by the inclusion of the second order effects.
