Good Agreement

Some formalisms which have frequently been used in general noncrossing electron transfer theories are examined and shown to be analytically equivalent. The accuracy of the numerical approximations is found to be surprisingly good, partly because different approximations tend to have opposite effects. The hydrogenic wave function assumption of the Rapp and Francis theory is found to be seriously inadequate and the theory is generalized to Coulomb wavefunctions of higher n value. When these wavefunctions are suitably normalized the magnitude and overall energy dependence of the cross section is in good agreement with experiment in alkali metal collisions where this type of collision is expected to be the dominant transfer process.

Good Agreement

The cross section for electron capture by Kr+ ions from rare gas atoms between 30 and 120 keV is found to be in good agreement with previous measurements where these exist, except for neon. The Rapp–Francis model gives an acceptable fit to the energy dependence of these and higher energy data but is too large by a factor of about five. In contrast the Landau–Zener model predictions are too large for helium and neon and too small for the heavier targets unless metastable states of krypton with large polarizabilities dominate the cross section.

Experimental Findings

This paper reports experimental results for the influence of target excitation and orbital alignment on the electron-transfer process in ion–Na(3s, 3p) collisions. Systematic experimental investigations with a range of simple ions reveal a similar behavior of the electron-transfer cross-section parameters as a function velocity. The experimental findings are compared with atomic and molecular orbital calculations.
