Population of ground and lowest excited states of sulfur via the dissociative recombination of SH+ in the diffuse interstellar medium

Résumé

Our previous study on dissociative recombination of ground state SH^+ through ^2Π states of SH is extended by taking into account the contribution of ^4Π states recently explored by quantum chemistry methods. Multichannel quantum defect theory is employed for the computation of cross sections and rate coefficients for dissociative recombination, but also for vibrational excitation. Furthermore, we produce the atomic yields resulting from recombination, quantifying the generation of sulfur atoms in their ground (^3P) and lowest excited (^1D) states, respectively.
