Annotation

An expression for the shock profile of a spectral line with allowance for nonelastic processes is obtained within the framework of the kinetic approach. The width and shift operator, corresponding to Stark broadening is governed by the behavior of the spectral density of low-frequency field fluctuations. Due to incorporation of the medium's polarization, the resultant expression does not contain a divergence corresponding to large impact parameters.
