Dissociative Excitation of Even Doublet Levels of the Cobalt Atom in Electron Collisions with Cobalt Dichloride Molecules

The dissociative excitation of the even doublet levels of the cobalt atom upon the collisions of cobalt dichloride molecules with 100-eV monoenergetic electrons was experimentally studied. Dissociative excitation cross sections for transitions from these levels turned out to be greater than the corresponding cross sections of direct excitation in electron-atom collisions (except for the e2P1/2 level). The total excitation cross sections (including the contribution of cascade population) were determined for ten levels.
