Abstract

New uranium hollow-cathode Fourier-transform spectra have been recorded between 1800 and 42 000 cm−1. Combined with earlier visible and ultraviolet spectra, these have led to 354 odd levels and 809 even levels of singly ionized uranium (U ii) belonging to four odd and six even configurations. High-resolution Fourier-transform spectra of an electrodeless discharge lamp containing 238UI4 and 234UI4 were used to measure splittings of more than 800 isotopic U ii doublets to an accuracy of ~0.001 cm−1. From these transition isotope shifts 114 odd- and 397 even-level isotope shifts were determined.
