Abstract

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