  1. Comparison of our experimental result for the He-like U 1s1/22p3/2 J = 2 → 1s1/22s1/2 J = 1 intrashell transition with the most recent theoretical predictions. All values are in eV. MCDF indicates the multi-configuration Dirac–Fock prediction. Uncertainties correspond to ±1 standard deviation. See text for more details.
