Description
The fusion-evaporation reaction 70Zn(12C, 1p3n) at beam energies of 60 and 65 MeV was used to populated the excited states in 78Br. The previously known level scheme has been extended and two new rotational bands have been identified. The triaxial particle-rotor model (PRM) was used for the analysis of the positive parity doublet bands in 78Br. The energy spectra E(I), energy staggering parameter S(I) = [E(I) − E(I − 1)]/2I and the intraband B(M1)/B(E2) ratios of the doublet bands have been calculated. Good agreement has been obtained between the calculated results and the available data. The positive parity doublet bands in 78Br have been tentatively interpreted as a pair of chiral bands based on the πg9/2⊗νg9/2 configuration.
