Enhancement of nuclear Schiff moments and time reversal violation in atoms due to combination of soft nuclear octupole and quadrupole vibrations

School of Physics,University of New South Wales,Sydney 2052, Australia(Dated: February 9, 2008)Nuclear forces violating parity and time reversal invariance (P,T -odd) produce P,T -oddnuclear moments, for example, the nuclear Schiff moment. In turn, this moment can inducethe electric dipole moment (EDM) in the atom. The contribution to the Schiff moment fromthe soft collective quadrupole and octupole vibrations in spherical nuclei is calculated inthe framework of the quasiparticle random phase approximation with separable quadrupoleand octupole forces. The values of nuclear Schiff moments predicted for odd
