Summary
Three, possibly four, regularly spaced rotational bands with large dynamical moments of inertia, which are consistent with known superdeformed bands in the Lu/Hf region, have been identified in ¹⁷⁴Hf. The states were populated in the ¹³°Te(⁴⁸Ca,4n) reaction at a beam energy of 194 MeV. The Gammasphere array detected the emitted gamma radiation. Ultimate cranker calculations predict substantial triaxial deformation (γ ≈ ± 17{sup o}) for highly deformed ¹⁷⁴Hf structures. However, ¹⁷⁴Hf is eight neutrons away from the previously established N = 94 triaxial superdeformed shell gap. Shell gaps at N = 100 and 106 with γ ≥ 15{sup o} are observed when {var_epsilon}₂ ≈ 0.45, which may be responsible for the predicted TSD minima in ¹⁷⁴Hf.
