Shape transition in Os and Pt isotopes
Journal Article

· Phys. Rev. C; (United States)
Ground state structure of the A = 186-196 Os-Pt region is investigated through a self-consistent Hartree-Fock-Bogoliubov calculation employing a pairing plus quadrupole plus hexadecapole model interaction Hamiltonian. The influence of the hexadecapole degrees of freedom on the triaxiality is especially examined. A gradual prolate to oblate shape transition is found in Pt isotopes but such a change is almost abrupt in Os at Aroughly-equal194. This difference in behavior of the Os and Pt isotopes is obtained only if all the hexadecapole degrees of freedom, instead of merely an axial Y40 component, are treated fully self-consistently.
