We define gravitational mass operator of a hydrogen atom in thepost-Newtonian approximation of the General Relativity and show that it doesnot commute with energy operator. Nevertheless, the equivalence between theexpectation values of gravitational mass and energy is shown to survive forstationary quantum states. Inequivalence between gravitational mass and energyat a microscopic level reveals itself as unusual electromagnetic radiation,emitted by the atoms, supported and moved in the Earth gravitational field,which can be experimentally measured. Inequivalence between gravitational massand energy at a macroscopic level results in time dependent oscillations of theexpectation values of gravitational mass for mixed quantum states.

Is Gravitational Mass of a Composite Quantum Body Equivalent to its Energy?
