A brief survey of available theoretical techniques is given for positron–atom scattering. The distinction between methods involving a finite number of target states and those with an infinite number of target states is emphasized. The situation regarding total cross sections is summarized, and a new, non-perturbative, eikonal-type approximation, based on the work of Wallace, is introduced.

New technique is presented for modeling the total cross sections of electron scattering by Na, K, Rb and Cs atoms in the low and intermediate energy regions. The calculations have been performed in the framework of genetic programming (GP) technique. The GP has been running based on the experimental data of the total collisional cross sections to produce the total cross sections for each target atom. The incident energy and atomic number as well as the static dipole polarizability have been used as input variables to find the functions that describe the total collisional cross sections of the scattering of electrons by alkali atoms. The experimental, calculated and predicted total collisional cross sections are compared. The discovered functions show a good match to the experimental data.

The four-body Born approximation is applied in post form to calculate the differential and total cross-sections for single electron capture from helium atoms by impact of the fast protons in the intermediate energy range. Theoretical results are obtained for hydrogen formation in ground state using full correlated accurate wave function for helium. The present results are compared with the results obtained from one parameter uncorrelated wave function to provide a clear visualization for the effect of electron correlation on the cross-sections. Comparison between the results for different wave functions shows the sensitivity of the processes on the electron–electron correlation especially at small scattering angles. The results are also compared with experimental data. The present calculated results show a general agreement with experimental finding for differential cross-sections and pursue the excellent trend with the measurement and other theoretical findings for total cross-sections.
