Spectra of a Holmium in the near-UV. II.
Listed in IVOA Registry (Virtual Observatory)
Fourier Transform spectra of Holmium (Ho) in the UV spectral range from 31530 to 25000cm^-1^ (317 to 400nm) have been investigated, particularly focusing on the ionic lines.
Description
The distinction between the different degrees of ionization (I, II, and III) is based on differences in signal-to-noise ratios from two Ho spectra, which have been measured with different buffer gases, i.e., neon and argon. Based on 106 known Ho II and 126 known Ho III energy levels, 97 lines could be classified as transitions of singly ionized Ho and 9 lines could be classified as transitions of doubly ionized Ho.
Of the 97 Ho II lines, 6 have not been listed in the extant literature. Another 215 lines have been assigned to Ho II, though they could not be classified on the basis of the known energy levels.
