摘要：
Spectra of neon-filled hollow cathode discharge lamps
were observed by means of high-resolution Fourier-transform spectroscopy
(FTS) covering the region from vacuum ultraviolet to near infrared. By
combining these new measurements with results of other FTS and grating
spectroscopy observations, we compiled a complete list of approximately 1700
spectral lines of Ne II covering the range from 324 Å to 130000 Å.
All known energy levels of Ne II were derived from this line list with
improved accuracy. The newly optimized energy levels were used to derive a
set of Ritz wavelength standards in the vacuum ultraviolet that are in good
agreement with the previously used data. An improved classification of
energy levels was made with the help of parametric calculations, and the
existing controversy in the naming of strongly mixed levels was resolved.
