The intermediate valence compounds (,Ir) exhibit an anisotropic magnetic susceptibility. We report measurements of the temperature dependence of the occupation number, , for as well as the magnetic inelastic neutron scattering spectrum at 12 and 300 K for . Both and were calculated for the Anderson impurity model with crystal field terms within an approach based on the noncrossing approximation. These results corroborate the importance of crystal field effects in these materials; they also suggest that Anderson lattice effects are important to the physics of .
