Triaxiality andγ-softness in196Pt

Abstract

The nuclear level structure and electromagnetic properties of196Pt were investigated withγ-spectroscopic techniques using multiple Coulomb excitation by208Pb projectiles. Particle-γ, and particle-γ-γ coincidences were measured over a wide range of scattering angles.E2-transition moments and static quadrupole moments have been determined by a comparison of experimental scattering-angle dependentγ yields with calculated yields in a largely model-independent procedure. The results are compared with different theoretical models: the Asymmetric-Rotor Model, the Generalized Collective Model, and the Interacting Boson Model. The best agreement is obtained with the Generalized Collective Model representing a triaxial nucleus which is soft in theγ degree of freedom.
