Inelastic collisions of slow electrons with CuCl molecules

An experimental investigation was made of inelastic collisions of slow electrons with copper monochloride molecules. When the electron energy was 100 eV, the excitation of molecular bands of CuCl was accompanied by dissociative excitation of spectral lines of the copper atom. The ratio of the dissociative excitation cross sections of the resonant and Beutler levels differed very greatly from the ratio of the same cross sections in the case of direct excitation in e — Cu collisions.
