摘要：

High energy magnetic inelastic neutron scattering measurements of intermultiplet transitions in rare earth and actinide metals have established the importance of intra-atomic correlations even in the presence of strong hybridisation. Well-defined transitions are observed up to an energy of 1766 meV in thulium metal. The 3H4→3F2 transition is observed across the alloy series U(Pd1-xPtx)3, showing that localized 5f2 excitations persist in the heavy fermion compound UPt3. The splitting of the spin-orbit transition in CeAl3 suggests that hybridisation is an important component in the crystal field potential. © 1990.
