Confirmation of $8^{+}$ assignment to the 11.86 MeV level in ${}^{24}{Mg}$

Linear polarizations of

γ

rays from the 11.86→8.12 →4.12 MeV decay in

{}^{24}{Mg}

have been studied with a NaI polarimeter. The 11.86 MeV level was populated via the

{}^{12}C ({}^{16}O, α γ) {}^{24}{Mg}

reaction. The results are consistent with

J^{π} = 8^{+}

for the 11.86 MeV level and in agreement with earlier work, rule against a

6^{+}

assignment with 85% confidence.
