摘要：

A theory describing collisions between arbitrary atoms or ions and atomic hydrogen is developed. Results are obtained in terms of amplitudes for electron-hydrogen and proton-hydrogen collisions and the arbitrary atom or ion transition form factor. No recourse to scattering by fictitious electron-plus-proton atoms is necessary. Applications are made to the differential and total cross sections for He+(1s)+H(1s)→He+(1s)+H(n=2). Agreement with recent measurements is obtained. A simple approximation to the results, σσpH(1s→n=2)+8σpH(1s→2s), is obtained and is in fair agreement with recent data. © 1979 The American Physical Society.
