On the basis of the Coulomb cut‐off potential model [2, 3] electrical conductivity calculations for a H‐Plasma are carried out in a temperature and density range 8000 K ⩽ T ⩽ 50000 K and 10 18 cm −3 ⩽ n e ⩽ 10 24 cm −3 . The electron‐ion scattering is included by the semiclassical result given in [2, 3], whereas the influence of the electron‐electron scattering is included by the well known Spitzer‐factor. The electron‐neutral interaction is modelled by a polarization potential [8] in Born‐approximation. The results for the electron‐ion interaction show a dependence only on the parameter Γ c = e 2 k B T/γr c , whereas the electron‐neutral interaction has a more complicated temperature dependence.
