We work out details of defining the spatial densities corresponding to thegravitational form factors of spin-0 and spin-1/2 systems using sphericallysymmetric sharply localized wave packets. The expressions for the spatialdensities are provided in the frames with both zero and non-zero expectationvalues of the momentum operator.
