Abstract : An approximate procedure is described for the theoretical calculation of the spectral absorption coefficient produced by bound-free andfreefree transitions in plasmas containing polyelectronic atoms and ions. This method of calculation is based on the assumption that only two ionized species make important contributions to the opacity and that these two ionic constituents are present in equal concentrations. The approximate formulae are shown to yield results that are in good accord with estimates based on detailed numerical computations. (Author)
