Article is review of works on nonequilibrium electron distribution function formation at a presence of sources and sinks in momentum space. The analitical investigations and numerical simulation of the nonlineat collision inte-grals of Boltzmann and Landau-Fokker-Planck has been considered. The experimental study results of nonequilibri-um electron distribution function formation in solid plasma at its irradiation by electromagnetic radiation or charged particles flows have been implemented.
