Abstract
Despite the more than 1 order of magnitude difference between the measured dipole moments in and , the octupole correlations in are found to be as strong as those in with a similarly large value of determined as The new results not only establish unambiguously the presence of a region of octupole deformation centered on these neutron-rich Ba isotopes, but also manifest the dependence of the electric dipole moments on the occupancy of different neutron orbitals in nuclei with enhanced octupole strength, as revealed by fully microscopic calculations.
