摘要：

Background: The existence of the electric dipole moment (EDM) of stable nuclei would be a direct evidence of the time reversal invariance violation (TRIV). Therefore, its measurement could be considered as a complement to the search for neutron and atomic EDMs. Purpose: To clarify theoretical issues related to calculations of EDMs in many-body systems we calculated the EDMs of the simplest nuclei. Method: For calculations of three-nucleon systems EDMs we used TRIV potentials based on the meson exchange theory, as well as the ones derived by using effective field theories (EFT) with and without explicit pions. Nuclear wave functions were obtained by solving Faddeev equations in configuration space for the complete Hamiltonians comprising both TRIV and realistic strong interactions. Results: The expressions for EDMs of He-3 and H-3 are given in terms of meson exchange couplings and low energy constants of EFT potentials. Conclusions: The obtained results are compared with the previous calculations of He-3 EDM and with time reversal invariance violating effects in neutron-deuteron scattering. The model dependence on strong interactions is discussed. DOI: 10.1103/PhysRevC.87.015501
