Dissociative excitation of the 2S°, 2P°, and 2D° levels of the cobalt atom in collisions of slow electrons with cobalt dibromide molecules

Abstract

The dissociative excitation of the odd doublet S, P, and D levels of the cobalt atom in collisions of slow electrons with cobalt dibromide molecules was studied experimentally. Eighty six dissociative excitation cross-sections were measured at an exciting electron energy of 100 eV. Two optical excitation functions were recorded at electron energies in the range 0–100 eV. The total dissociative excitation cross-sections were calculated for 20 levels based on the obtained results. The cross-sections of the formation of excited cobalt atoms in e–Co, e–CoBr₂, and e–CoCl₂ collisions were compared.
