Inelastic collisions of electrons with potassium chloride molecules, a
ccompanied by spontaneous emission in the region of the spectrum 0.19-
0.85 mum, were investigated by the method of extended crossed beams wi
th recording of an optical signal from the crossing region. It was est
ablished that for electron energies up to 100 eV the spectrum contains
the lines of KI, KII, KIII, ClI, ClII, and ClIII. The optical excitat
ion functions in the electron energy range 0-100 eV were recorded for
a number of lines of these objects. Regularities observed in the disso
ciative excitation processes in the course of the experiment are discu
ssed.
