The inelastic collision of protons with sodium atoms are treated for the first time within the framework of the coupled-static and frozen core approximations. The method is used for calculating partial and total cross-sections with the assumption that only two channels (elastic and hydrogen formation in 2s state) are open. In each case, the calculations are carried out for seven values of the total angular momentum ℓ(0 ≤ ℓ ≤ 6). The target is described using the Clementi Roetti wave functions within the framework of the one valence electron model. We use Lipmann–Swinger equation to solve the derived equations of the problem, then apply an iterative numerical method to obtain the code of computer to calculate iterative partial cross-sections. This can be done through calculating the reactance matrix at different values of considered energies to obtain the transition matrix that gives partial and total cross sections. The present results for total hydrogen (2s state) formation cross sections are in agreement with results of other available ones in wide range of incident energy.

We deal with the effect of polarization potentials on the inelastic scattering of protons by lithium atoms as a two-channel problem in which the elastic and hydrogen (2𝑠-state) formation channels are open at energies between 10 and 1000 keV. For this purpose, we improve the coupled-static approximation within the framework of the frozen-core picture of the target atom. We use the Lippmann-Schwinger equation and an iterative numerical method to obtain the computer code. This can be carried out by calculating the reactance matrix then to obtain the transition matrix that gives partial and total cross sections. Our results and those determined by previous researchers give reasonable agreement.
