  Using the quantum theory of linearized gravity, gravitational interaction
differential cross sections of one fermion by another fermion, a photon and a
scalar particle are calculated in the fermion rest-frame. Then, according to
the obtained results, it is shown that in the lab frame, the gravitational
interaction depends on the spin of the moving particle and is independent of
the spin of the rest particle. After that, on the dependency of the
gravitational interaction of fermion-photon upon the various states of photons
polarization is discussed.
