High-spin states and band structure inBr76

High-spin states of ${}_{}{}^{76}{}_{}{}^{}\mathrm{Br}$ have been investigated through observations of $\gamma$ rays produced in the ${}_{}{}^{66}{}_{}{}^{}\mathrm{Zn}({}_{}{}^{12}{}_{}{}^{}\mathrm{C},pn)$ reaction by bombarding an enriched ${}_{}{}^{66}{}_{}{}^{}\mathrm{Zn}$ target with 38.0-MeV ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ ions. Measurements were made of $\gamma$-ray singles and $\gamma -\gamma$ coincidence spectra, $\gamma$-ray angular distributions, and $\gamma$-ray linear polarizations. Level energies, decay modes, spins and parities, $\gamma$-ray branching ratios, and $\gamma$-ray radiative admixtures were deduced. There is evidence for a strongly excited $\Delta J=1\mathrm{}$ quasirotational band.
