The level scheme of 160Yb and the predicted SU(3)-O(6) transition in the N = 90 isotones
Abstract
The properties of the low-lying positive parity states of 16070Yb90 are reported and compared with predictions of the IBA-2 model based on parameters extrapolated from earlier calculations on the lighter, N = 90 isotones. There is good agreement between theory and experiment. The results confirm the predicted transition between the SU(3) and O(6) limits of the IBA for the N = 90 isotones, and point to a new region of O(6) symmetry.
