Levels ofKr86Fed in the Decay ofBr86

The decay of ${}_{}{}^{86}{}_{}{}^{}\mathrm{Br}$ has been studied with high-resolution Ge(Li) detectors by applying online mass-separation techniques to ${}_{}{}^{235}{}_{}{}^{}\mathrm{U}$ fission products. 19 transitions were positively assigned to this decay through half-life comparisons, and for 10 of them direct measurements of the half-life were performed, yielding an average value of 59 ± 4 sec. Levels for ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$ are proposed at ($\left(J^{\pi } \mathrm{within}\mathrm{parentheses}\right):1564.62\mathrm{}\pm 0.09 \mathrm{keV} \left(2^{+}\right), 2349.60\pm 0.14 \mathrm{keV} \mathrm{}(1,2), 2850.2\pm 0.4 \mathrm{keV}, 2926.24\pm 0.13 \mathrm{keV} \mathrm{}(1,2), 3099.20\pm 0.16 \mathrm{keV} \left(3^{-}\right), 4315.75\pm 0.17 \mathrm{keV} (2^{-},3^{-}), 5406.6\pm 0.5 \mathrm{keV} \mathrm{}(1,2), 5519.0\pm 0.9 \mathrm{keV} (1^{-},2^{-}), \mathrm{and} 6209.9\pm 0.5 \mathrm{keV} (1^{-},2^{-})$).
