The concept of gravitational radiation as a radiation of one level with the electromagnetic radiation is based on theoretically proved and experimentally confirmed fact of existence of electron’s stationary states in own gravitational field, characterized by gravitational constant K = 10⁴² G (G-Newtonian gravitational constant) and by irremovable space-time curvature. The received results strictly correspond to principles of the relativistic theory of gravitation and the quantum mechanics. The given work contributes into further elaboration of the findings considering their application to dense high-temperature plasma of multiple-charge ions. This is due to quantitative character of electron gravitational radiation spectrum such that amplification of gravitational radiation may take place only in multiple-charge ion high-temperature plasma. In elaboration of the authors’ works [1-4], an essential instantiation of the concept of fusion plasma’s steady states formation (as the last paragraph outlines) and boundary conditions refinement in the electron’s stationary-states-in-proper-gravitational-field problem are appended to this article.
