The Equation of Atom Motion in an External Gravitational Field
G. V. Basalyga, A. K. Gorbatsievich
Abstract
It is shown that the motion of a multielectron atom in an external gravitational field in a good approximation is described by system of the Mathisson-Papapetrou equations, if we put as a classical angular momentum of the atom the expectation value of the operator of the full angular momentum of the system, which includes spins of the nucleus and electrons, and orbital momentums of the electrons in the atom.
