The results were presented of Monte Carlo simulations of excitation and subsequent relaxation of the electronic sub-system of quartz in the close vicinity of a swift heavy ion trajectory. A comparison of numerical results and experimental detection of X-ray K-shell emissions of silicon atoms (KαLn transitions) from quartz aerogel irradiated with swift heavy ions demonstrated that no adequate description of the relaxation kinetics of the excited electronic subsystem of a solid in a swift heavy ion track could be possible without taking account of fast inter-atomic Auger processes which were absent in gaseous targets.
