Abstract:
In previous papers we have derived equations of motion with radiation terms and proved the existence-uniqueness of periodic solution of 2-body and 3-body problems of classical electrodynamics. The number of equations is more than the number of unknown functions – 8 in number for 2-body and 12 in number for 3-body problems. We have proved that two equations in the first case and three equations in the second one are consequences of the rest ones. These equations are used to determine the energy of moving particles (electrons). The main goal of the present paper is to estimate the energy of the moving electrons for Hydrogen-atom, Hydrogen-like atoms and Helium-atom.
