Enhanced population of high-<i>l</i>states due to the interplay between multiple scattering and dynamical screening in ion-solid collisions

Abstract

We present a study of the sub-shell populations of 13.6 MeV/u Ar17+ ions after transmission through thin carbon foils. We show that the combined effect of the wake field induced by the ion in the solid and multiple collisions leads to a strongly enhanced population of high angular momentum states. These results explain new experimental data for absolute total line emission intensities.
