Kinetic energy corrections for the free electrons in a high-frequency, fully-ionized plasma

It is found that, for a fully-ionized, homogeneous plasma in a high-frequency electric field, the fundamental term ₁ in the kinetic-energy correction is defined by the intensity and frequency of the electric field and by the collision frequency v₁. We obtain the Debye-Hükel energy correction in ₂, too, as did Theimer & Wright, but this term is much smaller than ₁, and its coefficient is no longer a constant.
