Abstract

Excited states of ⁸⁰Br have been investigated via the ⁷⁶Ge(¹¹B, α3n) and ⁷⁶Ge(⁷Li, 3n) reactions and a new δI=1 band has been identified which resides ~ 400 keV above the yrast band. Based on the experimental results and their comparison with the triaxial particle rotor model calculated ones, a chiral character of the two bands within the πg9/2⊗ νg9/2 configuration is proposed, which provides the first evidence for chirality in the A~80 region.
