“…The present work explores the possibility of producing more hydrogen through p-alkali atom collisions. In the present paper, the coupled static approximation (CSA) method, which is used by Elkilany [8][9][10][11], is modified to make it applicable to discuss the multichannel coupled static approximation (MCSA) problem (n = 4) of the collision of p-Li atoms at intermediate energies of the projectile. A numerical procedure is generalized to solve the obtained multicoupled equations.…”

The possibility of producing more hydrogen during p-alkali atom collisions is discussed. The coupled static approximation is modified for the first time to make it applicable to the multichannel problem of the collisions of p-alkali atoms. The formation of H (1s) and excited H (in 2s-and 2p-states) in the scattering of p-Li atoms is treated to test the convergence of our method. The modified method is used to calculate the total cross-sections of seven partial waves in a range of energy between 50 and 1000 keV. Our p-Li results are compared with earlier ones.

“…We determined the full forms of the core and static potentials by employing wavefunctions obtained by Clementi and Roetti [2] using a Roothaan-Hatree-Fock approach. This method is a modification of the two channels problem used in the effect of polarization in proton-lithium inelastic scattering [3].…”

The collisions of a proton with a lithium atom are treated for the first time as a three-channel problem under the assumption that the elastic and hydrogen formation in non-excited, H(1s), and excited, H(2s), channels are open. The effect of polarization potentials of the target and hydrogen formation is considered. A one-valence-electron model for the target, based on the Clementi–Roetti Slater-type basis functions, as well as a modified coupled-static approximation are used to calculate the partial and total cross sections of seven partial waves (0 ≤ ℓ ≤ 6, where ℓ is the total angular momentum) at incident energies between 50 and 500 keV. Our values of the total cross section are in good agreement with previous results.

“…Elkilany [9] investigated the effect of polarization potentials on antiproton scattered by positronium using a coupled static model. Elkilany [10,11] treated in detail the effect of polarization potentials on proton-lithium and muonhydrogen inelastic scattering as a two-channel problem using the improved coupled-static approximation.…”

Inelastic collisions of protons with rubidium atoms are treated for the first time within the framework of the three channel coupled static, and frozen core approximations. The method is used for calculating partial and total cross sections with the assumption that only three channels (elastic; non-excited hydrogen, 1s-state; and excited hydrogen, 2s-state) are open. We have used the Lipmann-Schwinger equation and the Green's functions iterative numerical method technique to solve the derived coupled integro-differential equations to obtain the computer code. The present results for total hydrogen formation cross sections are in agreement with results of other available ones in a wide range of incident energy. Résumé: Une étude des collisions inélastiques de protons sur des atomes de rubidium est présentée pour la première fois dans le cadre des approximations des trois canaux couplés-statiques et du coeur figé. La méthode est utilisée pour calculer les sections efficaces partielles et totale en supposant que seuls trois canaux sont ouverts : élastique, hydrogène dans le fondamental 1s et excité 2s. Nous utilisons l'équation de Lipmann-Schwinger et la technique numérique itérative des fonctions de Green pour solutionner les équations couplées intégro-différentielles dérivées afin d'obtenir le code d'ordinateur. Nos résultats pour les sections efficaces totales de formation d'hydrogène sont en accord avec d'autres résultats disponibles sur une large bande de l'énergie incidente.
