Shell model estimate of electric dipole moments in medium and heavy nuclei

Abstract

Abstract. It is evidence for an extension of the Standard Model in particle physics, if static electric dipole moments (EDMs) are measured for any elementary particle. The nuclear EDM arises mainly from two sources: one comes from asymmetric charge distribution in a nucleus and the other is due to the nucleon intrinsic EDM. We estimate the nuclear EDMs from two sources for the 1/2 + 1 states in Xe isotopes by a shell model approach using full orbitals between magic numbers 50 and 82.
