Anomalous isotope shifts in the chain of light Hg isotopes are investigated by using the Hartree Fock-Bogoliubov method with the Skyrme SIII, SkI3 and SLy4 forces. The sharp increase in the mean-square radius of the odd mass (181-185) Hg isotopes is well explained in terms of the transition from an oblate to a prolate shape in the ground state of these isotopes. We discuss the polarization energy of time-odd mean-field terms in relation to the blocked level by the odd neutron. (C) 2003 Elsevier B.V. All rights reserved.
