  Using numerical renormalization group method the temperature dependences of
the magnetic susceptibility $\chi(T)$ and specific heat $C(T)$ are obtained in
the single-impurity Anderson model with inclusion of the $d-f$ Coulomb
interaction. It is shown that the exciton effects owing to this interaction can
change considerably the dependence $C(T)$ in comparison with the standard
Anderson model at not too low temperatures, whereas the dependence $\chi (T)$
remains universal. The renormalization of the effective hybridization parameter
and $f$-level position, which is connected with the $d-f$ interaction, is
calculated, a satisfactory agreement with the Hartree-Fock approximation being
derived.
