Charge Transfer and Fine Structure Transitions in Kr⁺(²P_j)+Kr and Xe⁺(²P_j)+Xe Collisions

Abstract

Cross sections for charge transfer and fine-structure transitions within the ²P multiplet have been calculated for the Kr⁺(²P_J)+Kr(¹S₀) and Xe⁺(²P_J)+Xe(¹S₀) collisions by the impact parameter method. A previously published method for calculating the exchange energies and subsequently the charge transfer cross section for Ar⁺+Ar is improved to account for the larger spin-orbit splitting in these systems. Relative effciencies of the charge transfer process calculated for primary ions in the different fine-structure states ²P_3⁄2 and ²P_1⁄2 are found to agree closely with a recent experiment.
