Abstract
A theoretical description of multiphonon decay processes of highly excited localized modes is presented. Slowing of the decay rate at large vibration amplitudes and jumps in the relaxation rate at certain critical amplitudes are predicted. Highly excited vibrational states can appear in localized excitons in crystals of noble gases and can also appear in hot luminescence. The observed and calculated spectra of Xe *2 in a Xe crystal are compared.
