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 electron 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 of electron acceleration and to a change in the sign of the dc and low-frequency electrical conductivities.
