Abstract

Low-energy peak which appears in the energy dependence of total emission cross sections of light from the(3s 3p⁶)²S state of Ar⁺produced in charge transfer collisions of He⁺with Ar is accounted for on the basis of multi-channel systems. Calculation shows that the presence of “gecliptic”channel which crosses both the potential curves for the initial and the final states is essential to reproduce the profile of the low energy peak satisfactorily.
