Abstract
L-subshell ionization cross sections of Au and Bi induced by C2,3+ and O3+ ions have been measured for impact energies ranging from 0.25 to 0.79 MeV/u. The data have been compared with the Predictions of the EC PSSR [perturbed-stationary-state (PSS) theory with energy-loss (E), Co ulomb deflection (C), and relativistic corrections (R)] theory. Reason able agreement between theory and-experiment is observed for the L 1(2 s1/2) and L3(2p3/2) subshells. For the L2(2p1/2) subshell, however, la rge disagreement between the data and the ECPSSR predictions persists. This difference could be due to the ''collision-induced intrashell'' mechanism that was suggested by Sarkadi and Mukoyama [J. Phys. B 14, L 255 (1981)].
