ON THE POSSIBILITY OF GENERATION AND RECEPTION OF GRAVITATIONAL RAYS

The authors showed earlier that by means of a laser ray it is possible to excite harmonic oscillations of quadrupole mass moments of atomic electron shells. It follows from the theory of weak gravitational fields that this should lead to the generation of gravitational waves in the optical range by mass quadrupole electron shells. If the linear dimensions of the laser-excited specimen are much longer than the length of the generated gravitational waves, then the coherent part of the gravitational emission will have a sharp directivity, and it naturally should be called a gravitational ray. Generally, electromagnetic waves will be emitted together with the gravitational waves. This leads to the fact that only an insignificant share of the energy stored by the system from the laser beam will be in the form of gravitational waves. The authors investigate the feasibility of development of superemission gravitational and nonemission electromagnetic states of a system of N-particles with a descrete spectrum by using laser technology and excitation of particles in a two-quantum mode. An evaluation is made of the parameters, and requirements are defined for systems which may generate the detected force of coherent gravitational waves of optic and gamma frequencies. The fundamental circuit of a coherent gravitational ray receiver is described. Edited machine trans. of Izvestiya Vysshikh Uchebnykh Zavedenii. Fizika (USSR) v10 n9 p66-72 1967.
