Abstract (from CDS):

The spectrum of eight-times ionized iron, Fe IX, was studied in the 110-200 Å region. A low inductance vacuum spark and a 3 m grazing incidence spectrograph were used for the excitation and recording of the spectrum. Previous analyses of Fe IX have been greatly extended and partly revised. The number of known lines in the 3p53d-3p54f and 3p53d-3p43d2 transition arrays is extended to 25 and 81, respectively. Most of the identifications of the Fe IX lines from the 3p53d-3p43d2 transition array in the solar spectrum have been confirmed and several new identifications are suggested.
