Energy levels inBr77

$\gamma$ transitions in the reaction ${}_{}{}^{77}{}_{}{}^{}\mathrm{Se}(p, n\gamma ){}_{}{}^{77}{}_{}{}^{}\mathrm{Br}$ have been studied at proton energies between 2.150 and 2.850 MeV. Sixteen $\gamma$ rays were assigned to transitions in ${}_{}{}^{77}{}_{}{}^{}\mathrm{Br}$ below an excitation energy of ∼ 625 keV. Ten of these had not previously been reported. A previously reported 77 keV $\gamma$ ray was not observed. A level scheme was determined from threshold measurements, energy sums, and $\gamma -\gamma$ coincidence studies. This scheme includes five new levels located at energies of 167.0, 226.6, 336.9, 425.1, and 471.1 keV.
