摘要:
Line emissivities, effective recombination coefficients, opacity factors, departure coefficients and total recombination coefficients are calculated for hydrogenic ions with Z less-than-or-equal-to 8. Results are obtained for Cases A and B for n less-than-or-equal-to 50. Collisional transitions among individual n and l states are fully treated. Calculations 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 values, lying within the range 500 to 100 000 K, depending on the ion. All results are available in the form of machine-readable files. Secondary files containing only effective emissivities for transitions for n less-than-or-equal-to 25 and total recombination coefficients are also available for use with an interactive data server. The server produces tables of relative intensities of any two specified transitions or emissivities for any transition at all temperatures and densities in the data set. Extensive facilities for two-dimensional interpolation of relative intensities, emissivities and total recombination coefficients are provided.
