Abstract
Inelastic cross sections for the excitation, deexcitation, ion-pair formation, and mutual neutralization processes in cesium-hydrogen collisions $\mathrm{Cs}(6s,6p,5d,7s)+\mathrm{H}$ and $\mathrm{Cs}{}^{+}+{\mathrm{H}}^{\ensuremath{-}}$ 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 formation processes with the maximum values up to $23\phantom{\rule{0.16em}{0ex}}{\text{\AA{}}}^{2}$. Among the exothermic processes in the low-energy range, the largest partial cross section corresponds to the mutual neutralization process into the $\mathrm{Cs}(5d)+\mathrm{H}$ final state.
