Dissociative excitation of even states of tin atoms in e-SnCl2 collisions

Dissociative excitation of even levels of tin atoms in collisions of slow electrons with tin dichloride molecules is studied experimentally. The levels studied belong to the configurations 5s ²5pnp ^{1, 3} L (n=6, 7; L=S, P, D) and 5s ²5p 4f. Absolute values of cross sections for dissociative excitation at the electron energy of 100 eV are 1.05–2.56 times greater than cross sections for excitation in electron-atom collisions at the energy of 50 eV.
