Abstract

The dielectric function for a two‐component (hydrogen) plasma at arbitrary degeneracies is considered in the entire (k, w)‐space. Collisions are treated in Born approximation leading to a (k, w)‐dependent collision integral. Two possible limits are considered: (1) k → 0 (first), w → 0 (second) leading to the dc conductivity σ. (2) w → 0 (first), k → 0 (second) leading to the diffusivity D. The relation between σ and D is discussed.
