Datasets for Electron capture, excitation and ionization processes in He2+–H collisions in dense quantum plasmas

Abstract

Electron capture, excitation and ionization processes in He2+–H collisions taking place in quan- tum plasmas are studied by employing the two-center atomic orbital close coupling (TC-AOCC) method. The Debye-Hu ̈ckel-cosine (DHC) potential is used to describe the plasma screening effects on the Coulomb interaction between charged particles. The properties of eigenenergies of hydrogen-like atom with DHC potential are investigated as function of the screening length of the potential. It is found that the bind- ing energies of nl states decrease with decreasing the screening length of the potential. The dynamics of excitation, electron capture and ionization processes in He2+–H collision system is investigated when the screening length of the potential varies for a wide collision energy range. The TC-AOCC cross sections are compared with those for the pure Coulomb potential and, for the total electron capture, with the results of classical trajectory Monte Carlo method.
