Target dependence of charge exchange X-rays

摘要

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.
