Abstrakt: Iodine spectra were photographed in the 104 260- region with a triggered spark source. I IX and I X spectra were investigated. In the I IX spectrum earlier results J. Opt. Soc. Am. 70 , 1344 (1979) were confirmed, except that the 4d 8 ( 1 S 0 ) 2 P 3/2 level, 1 additional level in the 4d 8 5p configuration, 33 levels belonging to the 4d 8 4f configuration, and 2 levels of the 4p 5 4d 10 configuration were established. Fifty-five additional lines were classified in the I IX spectrum. In the I X spectrum the earlier values of 3 P 0 and 1 S 0 of the ground configuration 4d 8 and four levels of the odd-parity configurations J. Opt. Soc. Am. B 14 , 1013 (1997) were rejected. 3 P 0 and 1 S 0 of the ground-state configuration and five new levels of the odd-parity configurations were established. Sixteen new lines were classified in the I X spectrum. Hartree-Fock calculations with relativistic corrections and least-squares fit parametric calculations were carried out for both spectra for interpretation of the observed energy-level schemes. 1998 Optical Society of America S0740-3224(98)03107-5
