High spin states in the doubly oddBr72nucleus

States of ${}_{}{}^{72}{}_{}{}^{}\mathrm{Br}$ were studied through the ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$,$\mathrm{np}$) reaction at $E=40\mathrm{} \mathrm{to} 55$ MeV. From the excitation function, $\gamma$-ray angular distribution, $\gamma -\gamma$ coincidence and decay measurements, $\gamma$ rays depopulating states with probable spin values ranging up to $I=\left(9\right)\mathrm{}$ were found. An isomeric state of $T_{\frac{1}{2}}=10.3\mathrm{}\pm 0.6$ sec, and $I^{\pi }=\left(1^{-}\right)$ at 101.0 keV excitation energy was found. The observation of certain similarities with a recently reported band in ${}_{}{}^{74}{}_{}{}^{}\mathrm{Br}$ suggests that the collective features seen in heavier Br isotopes may persist in ${}_{}{}^{72}{}_{}{}^{}\mathrm{Br}$.
