- Аннотация: We consider electron impact single ionization of an atom near the Bethe ridge in the regime of large energy and momentum transfer. For evaluation of the ionization amplitude, a plane wave Born series is employed. A regularization procedure is utilized in circumventing typical divergences of the higher-order Born terms. The regularized Born series for the ionization amplitude is derived and, on this basis, renormalized analogues of the traditional plane wave Born and impulse approximations are developed. Numerical results using different approximations are presented and analyzed for the case of electron-hydrogen ionization. (c) 2007 Elsevier B.V. All rights reserved.
