摘要：

We have made a careful comparison of all available high-precision data for the 1s2s S-3(1)-1s2p P-3(0,1,2) transition energies for all nuclear charges ranging from helium (Z = 2) to uranium (Z = 92). Systematic discrepancies appear between theory and experiment for the J = 1 --> 0 transitions, but not for the J = 1 --> 1 and J = 1 --> 2 transitions. Analysis of laser-based high-resolution data (Z = 2, 3, and 5), beam-foil spectroscopy data (Z = 10-17), and hyperfine-quenched decay data (Z > 27) suggests an addition contribution to the P-3(0) energy equal to 2.3 (Z/10)4 cm-1.
