The transition quadrupole moments, Qt<\/sub>, of four weakly populated collective bands up to spin \u223c65\u210f in 157,158<\/sup>Er have been measured to be ∼11 eb demonstrating that these sequences are associated with large deformations. However, the data are inconsistent with calculated values from cranked Nilsson\u2013Strutinsky calculations that predict the lowest energy triaxial shape to be associated with rotation about the short principal axis. The data appear to favor either a stable triaxial shape rotating about the intermediate axis or, alternatively, a triaxial shape with larger deformation rotating about the short axis. These new results challenge the present understanding of triaxiality in nuclei.<\/p>\n","protected":false},"excerpt":{"rendered":"
