A plasma model for relaxation of a medium in heavy ion tracks in condensed matter is proposed. The model is based on three assumptions: the Maxwell distribution of plasma electrons, localization of plasma inside the track nanochannel, and constant values of the plasma electron density and temperature during the X‐ray irradiation. It is demonstrated that the plasma relaxation model adequately describes the X‐ray spectra observed upon interaction of a fast ion with condensed target. Preassumptions of plasma relaxation model are validated by the molecular dynamics modeling and simulation (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
