[en] An analysis of the Ne IV spectrum was undertaken in the 450–1100-Å spectral range. The spectra were produced by the beam–foil method with beam energies of 1.2 and 2.5 MeV, respectively. The resolution that was achieved, with a normal-incidence 2-m spectrometer, was sufficient to identify 53 new Ne IV lines and, consequently, to determine 18 new levels in the quartet and doublet systems and one sextet term. The energy values of 13 additional levels were also revised. The classification work was facilitated by the use of scaled relativistic Hartree–Fock calculations.
