Abstract: | In this paper we evaluate theoretically the modification of the distribution function of slow subthermal electrons heated
by radiation in a completely ionized plasma. The new solution we have found to the kinetic equation under conditions typical
of weak-collisional plasmas can be used to predict new nonlinear behavior arising from perturbations of the nonuniform electron
density and the coefficient of nonlocal heat transfer that depend on the intensity of the radiation heating the plasma, which
is absorbed via inverse bremsstrahlung. It is predicted that this new nonlinear behavior manifests itself at unexpectedly
small radiation intensities.
