Target dependence of charge exchange X-rays

Abstract

This paper describes our finding that in slow collisions of Kr 27+ projectiles with neutral Ne, Ar and O 2 atoms/molecules there is a significant target dependence in the spectra of X-rays originating from electron capture. We also present results of a classical trajectory Monte-Carlo (CTMC) calculation that quantifies the different initial electronic state ( n, l) distributions of the captured electrons for these three target gasses.
