Role of triaxiality in the ground-state shape of neutron-rich Yb, Hf, W, Os and Pt isotopes

The evolution of the ground-state shape of several isotopes of Yb, Hf, W, Os and Pt along the triaxial landscape is analyzed using the self-consistent Hartree-Fock-Bogoliubov approximation. Two well-reputed interactions (Gogny D1S and Skyrme SLy4) have been used in the study in order to assess to wh...
