Triaxial strongly deformed band candidate in N=90 160Yb

A high-spin rotational band has been observed in the N=90 nucleus 160Yb with very similar moment of inertia and decay characteristics to recently discovered sequences in 157,158Er which have been discussed in terms of strongly deformed triaxial structures. Well-deformed triaxial shapes are indeed expected in 160Yb at high spin and detailed cranked Nilsson-Strutinsky calculations have been performed from which possible configurations are discussed.
