Abstract

We present state selective experimental and theoretical results for electron capture in B-5+ and N5+-Li collisons at energies in the range of 1-10 keV amu-1. Experimentally we have used photon emission spectroscopy in the VUV and visible spectral range and theoretically we have performed classical trajectory Monte Carlo (CTMC) calculations. The influence of projectile-core electrons on electron capture processes in such highly charged ion-Li collisions has been investigated by comparing experimental data for He-like N5+ ions with both experimental and theoretical results for the fully stripped B5+ ions. We find that in the B5+ and N5+ cases the projectile-core electrons are of no direct importance for electron capture from Li by these ions. This allows us to compare the CTMC results for Be-4+-Li electron capture collisions with atomic orbital calculations as well as with experimental data for He-like C4+ colliding on Li.
