✦ Synopsis

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 3H, + 'F, transition is observed across the alloy series U(Pd,_,Pt,),, showing that localized 5f* excitations persist in the heavy fermion compound UPt,. The splitting of the spin-orbit transition in CeAl, suggests that hybridisation is an important component in the crystal field potential.
