Abstract 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.
