On the basis of all the available observations of the Ne VI spectrum, parti
cularly the new beam-foil spectra obtained at Liege University, approximate
ly 50 new line assignments are proposed and approximately 30 new energy lev
els are determined in Ne vr. All known energy levels have been improved, an
d a new value is proposed for the ionization potential. The new line identi
fications are supported by Hartree-Fock calculations combined with parametr
ic fitting of energies and transition rates. (C) 1999 Optical Society of Am
