On the basis of the remark that the gravitational interaction really acts with the binding energy, the emphasis is laid on the necessity of treating the gravitational interaction by the method of particle physics irrespective of the general relativity.
Accordingly, the interaction of a massless particle with spin 2 (graviton) is investigated by using the method which has been applied to the reformulation of quantum electrodynamics by the present author. As a result, we can formulate the theory of gravitational interaction in an unambiguous manner, in which the interaction of gravitational field with the binding potential is successfully derived.
The rotation of the perihelion is calculated by taking into account higher order corrections to the gravitational interaction, and a value which is about 8% smaller than the result of general relativity is obtained. This is exactly the value expected by Dicke and Goldenberg from their measurement of the solar oblateness.
As regards the behaviour of the photon in the gravitational field, our theory reveals some features different from general relativity. This difference, which concerns the universality of the coupling constant in our theory, will be tested by more precise experiments about the gravitational deflection of light or by experimnets about the change of light velocity in the gravitational field.
