Abstract

Time-reversal-violating interactions of the electrons and nucleus cause the appearance of new optical phenomena. These phenomena are not only very interesting from fundamental point of view, but give us a new key for studying the time-reversalviolating interactions of the elementary particles. Violation of time reversal symmetry has been observed only in K0-decay many years ago [1], and remains one of the great unsolved problems in elementary particle physics. Since the discovery of the CP-violation in decay of K0-mesons, a few attempts have been undertaken to observe this phenomenon experimentally in different processes. However, those experiments have not been successful. At the present time novel more precise experimental schemes are actively discussed: observation of the atom [2] and neutron [3] electric dipole moment (EDM) through either spin precession or light polarization plane rotation caused by pseudo-Zeeman splitting of atom (molecule) levels by external electric field − → E due to interaction of atom level EDM − → da with electric field W = − − → da · − → E [4, 5, 6, 7, 8](this effect is similar to magneto-optic effect Macaluso-Corbino [9]). It should be noted that the mentioned experiments use the possible
