Spectral classification of U ii energy levels using pattern-recognition techniques

Twenty-four unknown U i i energy levels are classified according to configuration using pattern-recognition methods. The energy level, Landé g factor, quantum number J, and ${}_{}{}^{234}{}_{}{}^{}\mathrm{U}$ isotope shift are used to describe each level. Preliminary results of the prediction of the extent of configuration mixing for low-energy odd levels are presented.
