Level scheme in 160Tm towards complete high-spin structure

摘要

High-spin states of 160Tm have been studied through the 146Nd(19F,5n) reaction at a beam energy of 102 MeV.The previously known πh11/2 (⊕)vi13/2 yrast band and πh11/2 (⊕)vh9/2 side band are confirmed,and several low-lying levels are observed.A 4-quasiparticle band feeding into the yrast band based on the π97/2(⊕)vh9/2(⊕)vi2/13/2 is suggested.Other two bands are observed and assigned to be based on the πd3/2(⊕)vi13/2 and π97/2 (⊕)vi13/2 configurations,respectively.
