L-Subshell ionization probabilities in very asymmetric ion-atom collisions - Schmidt-Bocking, H.; Ullrich, J.; Dorner, R.; Dexheimer, K.; Kelbch, S.; Dangendorf, V.; Schuch, R.; Zehendner, S.; Baptista, G.B.; Hagmann, S. (Elsevier)
The L-subshell ionization probabilities have been measured as a function of the impact parameter for proton on Sm, He on Pt, and Ne on Yb and Pt. For the light ions at very low velocities, the experimental Subshell ionization probabilities are in agreement with predictions of the SCA theory. For increasing velocity and increasing projectile nuclear charge, however, severe deviations between theory and experiment are observed. Possible reasons for these deviations could be an omission of collisional coupling between the L-substates, which is neglected in the SCA approach. For p on Sm also the impact parameter dependence of the L"I"I"I alignment tensor components have been measured. These alignment data also deviate strongly from predictions of the SCA theory.
