摘要：

We present an interpretation of published neutron inelastic scattering spectra in the Kondo lattices YbPd2Si2 and YbAgCu4 obtained in terms of the Anderson impurity model, describing the hybridisation of the 4f Yb electrons with the band electrons, and also including the crystal electric field interaction. In YbPd2Si2, the tetragonal crystal field parameters were determined. In YbAgCu4 the crystal field interaction was taken to exist by analogy with the isoelectronic compound YbAuCu4 where it has been identified. Both compounds can be described by a Kondo temperature T0=60 K and a Yb valency very close to 3.
