Abstract-Results are reported on a current investigation of the laboratory spectrum of Fe11 of astrophysical significance in the IUE range. The analysis is based upon high-resolution spectra in the region from 900 to 3750 A obtained with a hollow-cathode lamp at the 10.7 m normal-incidence spectrograph at the National Bureau of Standards, Washington, D.C., in combination with Fourier transform spectrometer data recorded by J. Brault at Kitt Peak and by R.C.M. Learner at Imperial College London. Some new levels and line transitions are presented for the 4p4d region of the normal system and for the doubly-excited 3d54s4d and 3d54p2 configurations.
