Analysis of the PdII spectrum in the ultraviolet and infrared regions

Research output: Contribution to journalArticle


The knowledge of the Pd II spectrum and term system has been extended by means of observations with Fourier transform and high dispersion photographic instruments in the infrared (8100 - 40000 Angstrom) and ultraviolet (1040 - 3100 Angstrom) regions. 320 lines have been classified and measured with high accuracy (+/-0.05-0.003 cm(-1) in the infrared, +/-0.002-0.0005 Angstrom in the ultraviolet). Together with the lines from a previous investigation (Physica Scripta 50, 110 (1994)), 916 Pd II lines are now classified and accurately measured. 56 new levels have been found, making the total number of known Pd II levels equal to 195. The level structure has been interpreted by means of parametric calculations. Fitted parameter values are presented.
