Level/Term Populations and Line/Multiplet Intensities Using an Improved Hybrid Model Bhatia, A. K. ; Kastner, S. O. Abstract An improved hybrid level/term calculation is employed to obtain C III level/term populations and line/fractional multiplet intensities over the extended range of electron density 4.0 less than or equal log Ne less than or equal 12.0, for column lengths L ranging from zero (optically thin) to 1020/sq cm (moderately optically thick), at electron temperatures Te approximately 40,000 K(log Te = 4.6), Te approximately 63,000 K (log Te = 4.8), Te approximately 79,500 K (log Te = 4.9), and Te = 100,000 K (log Te = 5.0). The tabulated results are relevant to the interpretation of space observations obtained over extended spectral ranges by new and planned facilities including the Hopkins Ultraviolet Telescope (HUT) and the Far-Ultraviolet Spectrographic Explorer (FUSE).
