The existence of the permanent electric dipole moment of a fundamental particle implies violation
of time reversal invariance. The electric dipole moment of a paramagnetic 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 wavefunctions. The contributions to the Schiff moment from one-particle and onehole
excitations turn out to be very different from orbital to orbital. It is also found that the
contributions from the core excitations are larger than other particle-hole contributions.
