Abstract
Line emissivities, effective recombination coefficients, opacity facto rs, departure coefficients and total recombination coefficients are ca lculated for hydrogenic ions with Z less-than-or-equal-to 8. Results a re obtained for Cases A and B for n less-than-or-equal-to 50. Collisio nal transitions among individual n and l states are fully treated. Cal culations were made for log N(e) = 2(1)14 for Case B and log N(e) = 2( 1)10 for Case A. The electron temperature takes between nine and 12 va lues, lying within the range 500 to 100 000 K, depending on the ion. A ll results are available in the form of machine-readable files. Second ary files containing only effective emissivities for transitions for n less-than-or-equal-to 25 and total recombination coefficients are als o available for use with an interactive data server. The server produc es tables of relative intensities of any two specified transitions or emissivities for any transition at all temperatures and densities in t he data set. Extensive facilities for two-dimensional interpolation of relative intensities, emissivities and total recombination coefficien ts are provided.
