Two Gammasphere experiments have been performed in order to establish the possible triaxial nature of strongly deformed (SD) bands in174Hf. A lifetime measurement, using the Doppler-shift attenuation method, confirmed the large deformation of the four previously observed bands in this nucleus with transition quadrupole moments ranging from 12.6 to 13.8 b. These values are significantly larger than those predicted for triaxial minima by ultimate cranker (UC) calculations. A thin-target,...[Show more]
