Description
High spin states of $^{82}$Br were studied by using the fusion-evaporation reaction $^{82}$Se ($^4$He, 1p4n) at beam energies of 65 and 68 MeV. 26 new transitions and 13 new levels were added into the previous level scheme, including a positive-parity band. With the earlier configuration assignment π9/2 ⊗ν9/2 to band 1 and the similar experimental features to the chiral doublet bands observed in $^{78}$Br and $^{80}$Br, the positive-parity doublet bands 1 and 2 in $^{82}$Br are therefore suggested as chiral doublet bands with the π9/2 ⊗π9/2 configuration. The interpretation was supported by the relativistic mean field theory and triaxial particle rotor model calculations.
