FIG. 1.

Diffusion and friction coefficients for collision off relativistic Maxwellian distribution as a function of momentum per unit rest mass. Solid lines are coefficients predicted by the weakly relativistic collision model while dashed lines are those by the fully relativistic one. These are for electron-electron collision. Electron temperature is 25 keV. Diffusion coefficients, and , are normalized to ; friction coefficient is normalized to , where .
