Notes:
A prescription for the inverse bremsstrahlung (IB) absorption coefficient is presented. The coefficient is derived in terms of a collision frequency that is found from a memory function kinetic formalism. The formalism admits limits that allow a rigorous definition of the coefficient when the plasma is weakly coupled and approximations that provide a reliable calculation when the plasma is strongly coupled. In the latter case, use is made of spatial distribution functions computed from the solution to the set of integral equations describing plasma correlations via the hypernetted chain approximation (HNC). A simple analytic result is compared with the HNC calculations. Results show that, as expected, the classical form for the IB absorption coefficient is of little utility when the plasma is strongly coupled. The theory presented here should provide reasonable predictions of the coefficient.
