Extended EUV and UV Spectrum of Ne II



Alexander Kramida, C M. Brown, Uri Feldman, Joseph Reader


The extreme ultraviolet (EUV) spectrum of Ne emitted by a Penning discharge has been recorded at high resolution with a 10.7 m grazing incidence spectrometer. Based on the recorded spectra 75 new Ne II lines have been observed between 286 and 325 , resulting in 35 newly classified levels. Previous identifications of two levels were revised. By using the new energy levels, 77 additional lines in the ultraviolet (UV) region 1350-4330 were identified in the NIST Pt/Ne atlas. The spectra on the 10.7 m grazing incidence spectrometer were recorded on tritium type image storage phosphor plates, the first use of this material for high resolution grazing incidence measurements.
