Av. Maksimov et al., NONLINEAR PROPERTIES OF A WEAKLY COLLISIONAL PLASMA AT LOW RADIATION INTENSITIES, Journal of experimental and theoretical physics, 86(4), 1998, pp. 710-716
In this paper we evaluate theoretically the modification of the distri
bution function of slow subthermal electrons heated by radiation in a
completely ionized plasma. The new solution we have found to the kinet
ic equation under conditions typical of weak-collisional plasmas can b
e 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 pla
sma, which is absorbed via inverse bremsstrahlung. It is predicted tha
t this new nonlinear behavior manifests itself at unexpectedly small r
adiation intensities. (C) 1998 American Institute of Physics.
