DISSOCIATIVE EXCITATION OF IODINE IN ELECTRON COLLISIONS WITH KI MOLECULES

Dissociative excitation of iodine atoms and single-charged iodine ions was studied using extended crossed beams with the detection of the op tical signal from the collision region. Eighteen cross sections for di ssociative excitation of II and 63 cross sections for III were measure d at an electron energy of 100 eV. Two optical-excitation functions fo r II and eleven functions for III were detected in the range of electr on energies 0 - 100 eV. The possible reaction mechanisms that lead to the excited states of iodine atoms and single-charged iodine ions at l ow electron energies were proposed.
