Abstract: (Elsevier)

The Hartree-Fock + BCS quadrupole-octupole deformation energy surface of 222 Ra, calculated with the Skyrme SIII interaction, presents a minimum for a non-zero value of the octupole moment. Our results suggest the existence of a quadrupole coupling which may account for the observed differences between the moments of inertia of the positive- and negative-parity bands.
