Electron impact ro-vibrational transitions and dissociative recombination of H2+ and HD+: Rate coefficients and astrophysical implications

Riyad Hassaine, Emerance Djuissi, Nicolina Pop +11

Context. Molecular hydrogen and its cation H+2 are among the first species formed in the early Universe, and play a key role in the thermal and chemical evolution of the primordial…

A theoretical study of the dissociative recombination of SH with electrons through the states of SH

D. O. Kashinski, D. Talbi, A. P. Hickman +5

A quantitative theoretical study of the dissociative recombination of SH with electrons has been carried out. Multireference, configuration interaction calculations were used t…

Rotational transitions induced by collisions of HD ions with low energy electrons

O. Motapon, N. Pop, F. Argoubi +6

A series of Multichannel Quantum Defect Theory-based computations have been performed, in order to produce the cross sections of rotational transitions (excitations $N_{i}^{+}-2 \r…

Dissociative recombination of NH: A revisited study

J. Zs Mezei, M. A. Ayouz, A. Orbán +6

Dissociative recombination of NH is explored in a two-step theoretical study. In a first step, a diatomic (1D) rough model with frozen NN bond and frozen angles is adopted,…
