The method of calculating the interzone light absorption coefficient in a semiconductor with Coulomb-like random field developed by Bonch-Bruevich is generalized by inclusion of multiphonon processes. A formula is obtained for the frequency dependence of the absorption coefficient in the optical tail range in the Condon approximation with neglect of frequency effect.
