Effects of particle-hole excitations to nuclear Schiff moments in Xe isotopes

Effects of particle-hole excitations to nuclear Schiff moments in Xe isotopes The existence of the permanent electric dipole moment of a fundamental particle implies violation of time reversal invariance. The electric dipole moment of a diamagnetic neutral atom is mainly induced by the nuclear Schiff moment. In this study the Schiff moments induced by the interaction which violates parity and time reversal invariance are calculated for various Xe isotopes using the shell-model wave functions. The contributions to the Schiff moment from one-particle and one-hole excitations turn out to be very different from orbital to orbital.
