Abstract
The strong potential Born approximation has been applied to evaluate the transition amplitude for the collision process in which a fast ion of charge ZP captures an electron from the K shell of an atomic target with nuclear charge ZT, where ZT ≥ZP. The transition amplitude has been evaluated analytically in terms of Gauss hypergeometric functions. No peaking approximation has been made. We have considered the K‐shell capture of electrons by high‐energy protons from Li, C, Ne, Na, and Ar. Our results for C, Ne, and Ar are in good agreement with the available experimental data.Keywords
