摘要

Hafnium spectra excited in vacuum spark sources of different setups and electric circuits were recorded on two high-resolution vacuum spectrographs. For the wavelength region 300-500 angstrom, a 10 m normal incidence spectrograph with a 3600 l mm(-1) grating was used at the Meudon Observatory. In the region below 350 angstrom, a 3 m grazing incidence spectrograph with a 3600 l mm(-1) grating was used at the Institute of Spectroscopy in Troitsk. A total of 189 lines in the region 193-474 angstrom were identified as transitions from the interacting excited even configurations 4f(12)5s(2)5p(6)5d+4f(12)5s(2)5p(6)6d+4f(13)5s(2)5p(5)(5d+6s)+4f(14)5s(2)5p(4)(5d+6s)+4f(14)5s5p(6) to the low-lying odd configurations 4f(13)5s(2)5p(6) and 4f(14)5s(2)5p(5). Fine structure splittings and relative positions of the odd terms were established, and 142 levels of the excited even configurations were found.
