Ym. Smirnov, EXTENDED CLASSIFICATION OF HOLMIUM SPECTRAL-LINES USING DATA OBTAINEDIN CROSSING BEAMS, Spectrochimica acta, Part B: Atomic spectroscopy, 49(5), 1994, pp. 469-474
The classification of holmium spectral lines is extended using results
from measurements of the effective excitation cross-sections by a met
hod of extended crossing beams. Totals of 107 spectral lines of Ho I a
nd 26 of Ho II have been newly classified.
