MONTE-CARLO SIMULATION OF THE CREATION OF EXCITED REGIONS IN INSULATORS BY A PHOTON

Different approaches to solution of the kinetic equations for relaxati on of electronic excitations (analytical, numerical solution of integr o-differential equations, and Monte-Carlo simulation) display the prop erties and evolution of the excited region created by the absorption o f a high-energy photon. The relaxation at the final stages of inelasti c electron-electron scattering determines the number of low-energy exc itations in CeF3. The number of close excitations around a core hole i n BaF2 rapidly increases after the absorption of photons with energy a bove 32 eV, which results in a faster decay of crossluminescene.
