G. Nave et al., ANALYSIS OF THE 3D(6)4S((6)D)6D SUBCONFIGURATION OF FE(I) BY LASER-ENHANCED IONIZATION AND EMISSION-SPECTROSCOPY, Physica scripta. T, 49(5), 1994, pp. 581-587
Laser-enhanced ionisation spectrometry has been used to confirm 36 lev
els within the highly-excited 3d(6)4s(6D)6d subconfiguration in Fe I t
hat have been established by grating spectrometry. The new levels are
used to identify approximately 200 lines in the UV grating and Fourier
transform spectra, most of which are also observed in the solar spect
rum.
