The Newtonian Potential of the Static Scalar Particle

In this article we obtain the Coulombian potential of spinor and scalar particle with the quantum field theory, there is no difference between the spinor and scalar particle. Similarly the Newtonian potential of spinor particle and scalar particle are also obtained with the quantum field theory, however it is found that the Newtonian potential of scalar particle is half of the Newtonian potential of spinor particle with same mass, it contradicts with the equality of gravitational and inertial mass. The Newtionian potential of the spinor particle can be used to obtain the Newtonian potentials of the sun,the earth and so on, therefore we suggest that it should be considered to be the experimental test of the gravitational theory of Einstein.
