Empirical regularities in behaviour of the cross sections of cadmium, dissociative excitation in the e-CdX2 (X = Cl, Br, I) collisions

Search for the empirical regularities in the behaviour of the cross sections of the cadmium, atom and single-charged ion dissociative excitation in the collisions of the slow-energy electrons with the cadmium halides molecules is initiated. The comparison of the cross sections at the electrons energy of 30 eV shows that the cross sections of the dissociative excitation for all the CdI and CdII transitions in case of the CdCl32 molecule are significantly lesser than of the direct one. The cross sections of the singlet and ion transitions in case of the CdI2 molecule behave likewise, whereas the cross sections of the triplet transitions dissociative excitation are by 2.16-3.60 time higher as by the direct one
