New measurements of 26 spectral lines of highly ionized Fe in the rang
e of 91-263 Angstrom have been carried out with a wavelength uncertain
ty of +/-5 m Angstrom. The Light source was the TEXT tokamak at the Un
iversity of Texas in Austin. Lines of Be-Like, B-like, C-like, and N-l
ike Fe are included, with visually estimated intensities, the best pre
vious measurements, and energy-level classifications. Level values are
derived from these wavelengths and from known magnetic dipole (M1) li
nes.
