We derive the equilibrium velocity distribution of low-energy particles in the spherically symmetric gravitational field and calculate the escape rate of low-energy particles in a container with a leak placed in the spherically symmetric gravitational field. They can serve as the tests of Einstein's theory of gravitation.10 pages with no figureGeneral Relativity and Quantum CosmologyStatistical Mechanicstext
