  The theory of the quasielastic magnetic scattering of neutrons at the spin
liquid with RVB (resonance valence bonds) correlations is presented.
Calculations demonstrate that the dependence of the scattering cross section on
the energy transfer reproduces experimental shape of quasielastic peak in heavy
fermion systems. It is shown that Fermi statistics of the spin liquid
elementary excitations leads to the oscillations of the quasielastic scattering
total cross section as a function of the momentum transfer.
