Theoretical studies of L3-subshell alignment induced by heavy ions

Research output: Contribution to journalArticle

Abstract

The recent efforts made in the theoretical description of the anisotropy of the charge cloud of the L3 subshell induced by heavy ions in heavy atoms are reviewed. For L-shell ionization processes the strong dynamical couplings among the substates represent a serious challenge to the theory. This is exemplified by results of L3-subshell alignment calculations made in the first- and second-order Born approximation, as well as in a coupled-states scheme. The application of the perturbative variational method is briefly discussed as a possible way of future development in treatment of the collisional alignment.
