Abstract
Excited states of 80Br have been investigated via the 76Ge(11B, 3n) and 76Ge(7Li, 3n) reactions and a new I = 1 band has been identified which resides 400 keV above the yrast band. Based on the comparison between the experimental results and the triaxial particle rotor model calculations, a chiral character of the two bands within the pi g9/2 X nu g9/2 configuration is proposed, which provides the first evidence for chirality in the A 80 region.
