Scaling for state-selective charge exchange due to collisions of multicharged ions with hydrogen

Abstract

In this article we evaluate state-resolved charge exchange cross sections for Be4+, B5+, C6+, N7+, and O8+ projectiles colliding with atomic hydrogen employing two different methods: the classical trajectory Monte Carlo and the eikonal impulse approximations. These cross sections are used to extend previously derived scaling laws for n-, nl-, and nlm-distributions to highly excited final levels with 4 <= n <= 9, covering energies in the range 50 - 2000 keV amu. Present total and partial capture cross sections are in agreement with available experimental and theoretical data for these collision systems. Besides, the proposed scaling rules are also verified by other theories, becoming a useful instrument for plasma research.
