Abstract

The symmetric-eikonal model for single excitation of multielectronic targets is extended to include HartreeFock-Slater initial and final bound states. These wave functions are obtained by solving numerically the time-independent Schrödinger equation with a model potential. Total cross sections for excitation of He(1 1 S) and He(2 1 S) by proton impact are presented in comparison with available experimental data and other theoretical models. The model gives an accurate description at intermediate and high impact energies. Results are also presented for excitation of two-electron heavy ions and for alkaline targets.
