Oscillations inCs++ Cs andK++ K Charge-Transfer Cross Sections

Abstract

Charge-transfer cross sections of ${\mathrm{Cs}}^{+}$ + Cs and ${\mathrm{K}}^{+}$ + K are calculated by the impact-parameter method using suitable atomic wave functions. The theoretical cross sections as a function of ion velocity show oscillatory structure in qualitative agreement with the experimental values given by Perel and co-workers.
