Description
Summary:A new series of computations has been performed to obtain cross-sections and rate coefficients for state-to-state rotational transitions in the H... ion, induced by collisions with very low-energy electrons. Following our recent work on the HD+ ion (Motapon et al. 2014), and using the same molecular structure data sets, excitations ... for ... to 10, and de-excitations ..., for ... to 10, in the energy range 0.01 meV-0.3 eV, have been explored. The calculated cross-sections have been convolved in order to obtain Maxwell rate coefficients for electronic temperatures up to a few hundred of Kelvin. Moreover, Maxwell rate coefficients for dissociative recombination have been calculated for the same initial rotational levels. (ProQuest: ... denotes formulae/symbols omitted.)
