Three, possibly four, regularly spaced rotational bands with large dynamic moments of inertia have been identified in 174Hf. Their properties are consistent with known triaxial superdeformed bands of the Lu/Hf region. Calculations predict substantial triaxial deformation (γ ≈ γ17°) for 174Hf structures with deformation ε2 0.45, despite the fact that 174Hf is eight neutrons away from the previously established N = 94 triaxial superdeformed gap. Shell gaps at N = 100 and 106 with γ ≥15° are...[Show more]
