Abstract
Symmetric resonance charge‐exchange cross sections are calculated, in the quasiclassical approximation. Previous calculations of the same type, due to Rapp and Francis, give systematically lower cross sections than the experimental ones. It is suggested that this is a result of the rough form of the atomic wavefunctions used by Rapp and Francis. Here, Hartree–Fock–Slater wavefunctions are used. The necessary integrations are done numerically. On the average, much better agreement with experimental results is achieved. The calculations were performed for He, K, Cs, and Hg.
