THE FE-XIV SPECTRUM - PREDICTED LINE-INTENSITIES AND SOLAR IDENTIFICATIONS

Level populations and line intensities have been calculated in a 40-level model of Fe XIV which includes the configurations 3p3 and 3s3p3d. The results have been compared against intensities of weaker, unidentified, or tentatively classified lines in published solar line lists including a recent GSFC/SERTS high-resolution list, and in presently measured archival NRL/S082A active region spectra. Seven new lines are identified as Fe XIV transitions; five other observed, unidentified lines are considered to be Fe XIV transitions on the basis of wave-length coincidence, but require further observations to obtain photometric intensities for verification; one line at 216.93 angstrom is shown to be due to some other ion than Fe XIV. In addition, a unique forbidden infrared (congruent-to 1.25 mum) line originating in the high metastable level 3s3p3d(F-4(9/2)) is found to have an unusual intensity dependence on electron density.
