High-spin states inCl37

The deexcitation of high-spin states in ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$ was studied via the ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}({}_{}{}^{19}{}_{}{}^{}\mathrm{F}, 2\alpha p)$, ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}({}_{}{}^{12}{}_{}{}^{}\mathrm{C}, 2p)$, and ${}_{}{}^{34}{}_{}{}^{}\mathrm{S}(\alpha , p)$ reactions. The decay scheme and spin assignments were deduced from $p-\gamma$ coincidences, $\gamma$-ray angular distributions, directional correlation from oriented nuclei ratios, and excitation function measurements. The lifetime of a new yrast level at 7020 keV ($J=\frac{15}{2}$) was determined in a recoil distance experiment. New levels are reported at 6001 keV ($J=\frac{9}{2}-\frac{13}{2}$) and at 8177 keV. The observed levels are compared to the predictions of the weak-coupling model.
