Formation of 2s-State Hydrogen Atom in Proton-Lithium Inelastic Scattering

Abstract

Elaborate coupled static formalism is employed for treatment of proton-lithium collisions at wide range of incident energies between 10 and 1000 Kev. Coupled static and frozen core approximations are employed for calculating partial and total cross sections. Only elastic and formation of excited hydrogen, H(2s), channels are considered. Total cross sections are calculated using seven partial waves Green’s function expansion technique of total angular momentum ℓ (0≤ℓ≤6). Proposed iterative approach allows for reliable representation of the core potentials using elaborate variational calculation of target orbitals. Polarization potential of lithium atom is taken into consideration in calculating corresponding total cross sections. Quite interesting reliable results were obtained in comparison with other theoretical approaches.

Elastic Scattering of e+-K-atom

“…This is expected. The curve D which represents MGA-SPSM results of Khare and Vijayshri [3,7] is closer to curve A up to 60 • angle of scattering. But…”

Effect of Polarization Potential on Proton–Sodium Inelastic Scattering

“…It is obvious from Eqs. (11) and (12) that the solutions can be only found iteratively and the ν th iteration are calculated by :…”

“…The effect of switching on various polarization potentials on antiprotonpositronium inelastic scattering is investigated in detail. Elkilany [11] employed an elaborate coupled static formalism for the treatment of proton-lithium collisions at wide range of incident energies, between 10 and 1000 keV. Only elastic and formation of excited hydrogen, H(2s), channels are considered.…”

Theory and application of hydrogen formation in proton-alkali atom collision

“…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.…”
