Abstract
The excitation spectra in the multi-band periodic Anderson model with the crystalline electric field (CEF) are investigated within the self-consistent second-order perturbation theory. It is shown that the k -dependence of the hybridization, V( k) , reflecting the symmetry of the lowest CEF level, is essential to explain the low-energy properties, even if the CEF splitting cannot be observed by the neutron scattering, such as the Kondo semiconductor, CeNiSn.
