Abstract

High-resolution grating and Fourier transform spectroscopy measurements, using hollow-cathode and electrodeless discharge lamp sources, have resulted in a list of 92000 lines of Ui and Uii. The wave-number accuracy is about 0.003 cm−1. With this list and new Zeeman structure, isotope-shift, and 233U hyperfine-structure spectrograms, we have found 500 new Ui levels. We now know 1240 even levels between 7020 and 42000 cm−1 and 360 odd levels up to 38000 cm−1. All levels expected to lie below 10000 cm−1 have been found. Levels of five odd configurations (f3ds2, f3d 2s, f4sp, f3ds8s, f4dp) and seven even configurations (f4s2, f2d2s2, f3s 2p, f3dsp, f4ds, f3d 2p, f3ds8p) are now known.
