  The momentum transfer dependence of the magnetic form factor associated with
the quasielastic spectral component in the dynamic magnetic response of
intermediate valence SmB$_{6}$ has been measured using inelastic neutron
scattering on a double-isotope ($^{154}$Sm, $^{11}$B) single crystal. The
experimental dependence differs qualitatively from those obtained earlier for
the inelastic signals, as well as from the field-induced magnetic form factor
of SmB$_{6}$ obtained by polarized neutron diffraction. This observation is
interpreted by specifically considering the Curie-type contributions to the
dynamic susceptibility, which arise from the mixing of 4f$^{5}$ and 4f$^{6}$
J-multiplets into the intermediate valence state wave function.
