  We examine a relevance between characteristic of crystal field structures and
heavily renormalized quasiparticle states in the $f^0$-$f^1$-$f^2$ Anderson
lattice model. Using a slave-boson mean-field approximation, we find that for
$f^2$ configurations two or three quasiparticle bands are formed near the Fermi
level depending on the number of the relevant $f^1$ orbitals in the $f^2$
crystal field ground state. The inter-orbital correlations characterizing the
crystal field ground state closely reflect in inter-band residual interactions
among quasiparticles. Particularly in the case of a singlet crystal field
ground state, resulting residual antiferromagnetic exchange interactions among
the quasiparticles lead to an anomalous suppression of the quasiparticle
contribution of the spin susceptibility, even though the quasiparticle mass is
strongly enhanced.
