| Abstract: | A non-relativistic calculation of the free-free opacity is made in detail for the conditions of intermediate and strong electron degeneracy. Corrections to the Born approximation are included and the ion correlations as well as the electron screening of the nuclear charge are taken into account. The free-free opacity is compared with the conductive one. It is shown that it must be taken into account when the degeneracy is not too strong, that is in the temperature-density regime where the plasma frequency ω p satisfies the condition ω p ? 2.5kT. |
