Analysis of the PdII spectrum in the ultraviolet and infrared regions

The knowledge of the Pd II spectrum and term system has been extended by me ans 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 Angstr om in the ultraviolet). Together with the lines from a previous investigati on (Physica Scripta 50, 110 (1994)), 916 Pd II lines are now classified and accurately measured. 56 new levels have been found, making the total numbe r of known Pd II levels equal to 195. The level structure has been interpre ted by means of parametric calculations. Fitted parameter values are presen ted.
