To calculate the power of gravitational radiation, it is necessary to set the tensor of the mass distribution of the emitting system Qij.In this case, the order of the gravitational radiation power is determined by the numerical value of the constant G (Newton's gravitational constant).The gravitational radiation power calculated in this way is taken as a value that is supposed to be detected experimentally.But this method of calculating the power of gravitational radiation is completely unreasonable.The laws of gravitational radiation (like any radiation) are quantum personality.The emitting system must be in certain quantum states.Only the calculation of such states (transitions between which cause radiation) can give a correct estimate of the spectrum and power of gravitational radiation. The quantum nature of gravitational radiation with numerical estimates for such a radiation source as an electron is considered in the published work S I Fisenko Journal of Physics: Conference Series,(Volume 1557),012019, IOP Publishing doi:10.1088/1742-6596/1557/1/012019 ( Title: On the issue of gravitational radiation and thermonuclear fusion), 2020), and also [1,2].At the same time, it turned out that there are stationary states of the electron in its own gravitational field characterized by a gravitational constant K = 1042G (G - the Newtonian gravitational constant) and the irreducible curvature of space-time Λ.The fact of the existence of gravitational radiation as radiation of the same level as electromagnetic radiation is confirmed experimentally.In the work of the authors Haines, M. G. et al. Viscous Heating at stagnation in Z-Pinches. PRL 96, 075003-075008 (2006) provides data on the broadening of the characteristic emission spectra of multielectronic atoms.Such broadening of the characteristic radiation spectra can only be caused by an additional mechanism, such as the presence of excited states of electrons in their own gravitational field.In Bulbul, E. et al. Detection of An Unidentified Emission Line in the Stacked X-ray spectrum of Galaxy Clusters. arXiv http://arxiv.org/abs/1402.2301 (2014), as well as [3]. a radiation line unrelated to electromagnetic radiation was detected in the X-ray spectrum. This line, unlike other identified lines of electromagnetic radiation, cannot be attributed to any atomic transition. The energy spectrum of an electron in its own gravitational field and the energy spectra of multi-electron atoms are such that a resonance of these spectra occurs. The result of this resonant interaction is the appearance, including new lines, of electromagnetic transitions that are not associated with atomic transitions. In [1,2], the electron energy spectrum in its own gravitational field is given.The numerical values of these energies mean that
