Theoretical study of electronic excitation, ion-pair formation, and mutual neutralization in cesium-hydrogen collisions

Résumé

Inelastic cross sections for the excitation, deexcitation, ion-pair formation, and mutual neutralization processes in cesium-hydrogen collisions Cs(6s,6p,5d,7s) + H and Cs + + H − are calculated by means of the recently proposed branching-probability-current method and the recently calculated accurate ab initio adiabatic potential energies. Scattering calculations are performed in the low-energy range from 0.01 eV to 1 keV. It is shown that among the endothermic processes, the highest values of the partial cross sections correspond to the ion-pair forma-tion processes with the maximum values up to 2 A 2 . Among the exothermic processes in the low-energy range, the largest partial cross section corresponds to the mutual neutralization process into the Cs(5d) + H final state.
