Angular correlation and gamma ray linear polarization measurements inAl29

The decay scheme of ${}_{}{}^{29}{}_{}{}^{}\mathrm{Al}$ has been investigated with the ${}_{}{}^{26}{}_{}{}^{}\mathrm{Mg}(\alpha ,p){}_{}{}^{29}{}_{}{}^{}\mathrm{Al}$ reaction at $E_{\alpha }=14.2\mathrm{}$ MeV. Simultaneous measurements of $p-\gamma$ angular correlations and $p-\gamma$ linear polarizations, utilizing a three-detector Ge(Li) Compton polarimeter, have been accomplished. Spin-parity assignments of ${7/2}^{+}$, ${3/2}^{+}$, ${5/2}^{+}$, ${9/2}^{+}$, ${5/2}^{+}$, and ${7/2}^{+}$ are set forth, respectively, for the 1.75, 2.22, 3.18, 3.58, 4.22, and 5.99 MeV levels. The results suggest $J^{\pi }={\frac{11}{2}}^{+}$ for the 5.85 MeV level.
