New Energy Levels and Classifications of Spectral Lines From Neutral and Singly-Ionized Dysprosium (Dy I and Dy II)
Gillian Nave, Ulf Griesmann
We present over 4000 new energy-level classifications in the spectra of neutral and singly ionized dysprosium. These lines were observed using Fourier transform spectrometry of high current hollow cathode lamps, and cover the wavelength range 23 nm to 1.6 υm. They were classified using 43 new energy levels of DY I and 22 new energy levels of DY II. The standard uncertainty of the energy levels and the strongest lines is estimated at 0.005 cm-1.OCIS codes: 300.6300 Spectroscopy, Fourier transform; 300.6210 Spectroscopy, atomic
