Description
The excited states of 162Yb have been studied at iThemba Laboratory for Accelerator Based Sciences (iThemba LABS), using the 150Sm (16O, 4n)162Yb fusion-evaporation reaction. The beam of 83 MeV 16O was provided by the Separated-Sector Cyclotron (SSC) and used to bombard a 3 m/cm2 150Sm target. The &gamma -rays emitted from the reaction products were detected using the AFRODITE &gamma -ray spectrometer, comprised of 8 Compton-suppressed clover detectors. Attempts have been made to identify the low-lying excited states in 162Yb. Many levels have been found. In particular the first excited 02+ band and the even and odd sequences of the &gamma band have been firmly established. The 02+ band and the even spin members of the &gamma band are observed to exhibit a Laundau-Zenner crossing. This crossing demonstrates that the signature splitting in &gamma bands is mainly caused by band mixing. The data will be discussed in terms of the Triaxial Projected Shell Model and also with the predictions of the 5-Dimensional Collective Model (5-DCM).
