Title: [ital L]-subshell ionization cross sections in gold and bismuth by 3. 6--9. 5-MeV carbon and 4. 0--7. 2-MeV oxygen ions

Abstract

[ital L]-subshell ionization cross sections of Au and Bi induced by C[sup 2,3+] and O[sup 3+] 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 ECPSSR [perturbed-stationary-state (PSS) theory with energy-loss (E), Coulomb deflection (C), and relativistic corrections (R)] theory. Reasonable agreement between theory and experiment is observed for the [ital L][sub 1](2[ital s][sub 1/2]) and [ital L][sub 3](2[ital p][sub 3/2]) subshells. For the [ital L][sub 2](2[ital p][sub 1/2]) subshell, however, large 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, L255 (1981)].
