摘要：

Photoemission data of UT2Si2 (T = Ru, Rh, Pd, Ir) and the localized U-system UPd3 are presented. U 4f-core level spectra are compared with many-body calculations which reveal, that the U 5f-hybridization decreases from Ru to Pd. With increasing 5f-localization a second peak at EB = 0.5 eV with a hybridization dependent weight can be observed in the partial U 5f-spectra, which can be ascribed to strong electron-electron correlations. © 1990.
