Abstract
Linear-polarized soft-x-ray absorption (XAS) and inelastic neutron scattering (INS) experiments have been performed on with , Ir, and Co to determine the crystal-field scheme and characteristic Kondo temperatures for the hybridization between and conduction electrons. The ground-state wave functions are determined from the polarization-dependent soft-XAS data at the cerium edge and the crystal-field splittings from INS. The characteristic temperature has been determined from the line widths of the neutron scattering data. We find that the quasielastic linewidths of the superconducting compounds and are comparable with the low-energy crystal-field splitting.
