Comparison of experimental and theoretical binding and transition energies in the actinide region

Abstract

The present status of experimental and theoretical binding and transition energy determinations is reviewed. Experimental data and the most recent theoretical predictions are compared for the energies of K..cap alpha../sub 1/ X-rays, M series X-rays, K-LL Auger electrons, K, L/sub 3/, M and N levels, and the 4f spin-orbit splitting. In addition, the K..cap alpha../sub 1/ and L/sub 3/ data are fitted by Moseley-type diagrams, and data on the shallow levels and the valence bands of actinide oxides are discussed. Comparison shows that the single-particle Dirac-Fock theory and the inclusion of quantum-electrodynamic contributions predicts energies of the innermost levels generally within the accuracy of data, that is in the order of magnitude of 1 eV. However, in the N, O... shells large deviations do occur presumably due to strong many-electron interactions. The inclusion of many-electron effects in the relativistic theory remains a challenge, as do experimental investigations affording an accuracy of better than 1 eV for the various electronic levels.
