ANOMALOUS KINETICS OF PLASMAS IN HIGH-POWER RADIATION-FIELDS

Transport equations are obtained in the nine-moment approximation for plasmas in intense radiation fields where the amplitude of the electro n oscillations in the electromagnetic field exceeds the thermal speed. It is shown that for plasmas with a high degree of ionization, Z, the electron thermal conductivity is higher by approximately a factor of Z. The change in the frictional force on electrons colliding with ions owing to the effect of the radiation field leads to the possibility o f electron acceleration and to a change in the sign of the de and low- frequency electrical conductivities.
