DISSOCIATIVE EXCITATION OF K AND K-IMPACT ON KI MOLECULES( EMISSION BY ELECTRON)

Inelastic collisions of the slow monokinetic electrons with the KI mol ecules have been investigated using the method of extended crossing be ams with recording an optical signal from the intersection region. The dissociative excitation cross sections for K and K+ lines are measure d at the 100 eV electron energy. It is found that for K the dependence of the dissociative excitation cross sections from the principal quan tum number is described by the power law. The optical excitation funct ions are recorded in a range of electron energies 0 to 100 eV. Probabl e reaction mechanisms at the low electron energies are briefly discuss ed.
