Description

High-spin states of 160Tm are studied by the 146Nd(19F, 5n) reaction at a beam energy of 102 MeV. The previously known πh11/2 ⊕νi13/2 yrast band and πh11/2 ⊕νh9/2 side band are confirmed. The level scheme is enriched and more low-lying levels are observed. A new side band is observed and assigned as the favoured signature partner of πd3/2 ⊕νi13/2. The spin of this band is assigned with the energy level systematics. It is pointed out that the B(M1)/B(E2) ratios increase rapidly at the high frequency approaching the second crossing in the πh11/2 ⊕νi13/2 band, which is closely related to the alignment gain of the aligned i13/2 quasineutron.
