Abstract
The excitation process of energetic ions, reflected at grazing angles from a metallic target, is assumed to be an electron-loss-capture-sequence. The density operator at the time of the last capture is factorized into an anisotropic part for the optical electron and an isotropic part for the inner electrons. Parentage approximation andLS-coupling then give the orientation for all levels of a supermultiplet. The circular polarized light, emitted during transitions from these levels, can be well fitted, with exception of lines fromL=0 terms. This shortcoming is removed by an extended model. This suggests that the parent ions, too, are oriented.
