Ratio of fast-to-slow components in BaF/sub 2/ emission is studied theoretically as a function of particle type and energy. The investigation is based on the model of crossluminescence quenching due to interaction between excitations in the track region. It is shown that even weak interaction between excitations can quench crossluminescence. We simulate the evolution of spatial distribution of electronic excitations (electrons, valence and core holes, excitons) in the track region for various energy deposits per unit track length. The system of kinetic, equations includes transformation, recombination and space diffusion of electronic excitations with account for electric fields originated due to charge separation in the track region. The results of this simulation allow us to explain the decrease of fast-to-slow emission ratio with energy and type of incident particle (in raw electrons-pions-protons-alpha-particles).
