Abstract A new angular correlation analysis technique for assigning spins to $alpha$-unbound states of nuclei that feed $alpha$-unbound states of other nuclei is described. A kinematically complete experiment was performed to study the reaction $^{12}$C($^{16}$O,$alpha$)$^{24}$Mg$^*$, populating $alpha$-unbound states of $^{24}$Mg that decay to $alpha$-unbound states of $^{20}$Ne, where all final state particles were detected. The new analysis technique was used to unambiguously identify the first $I^{pi}=12^+$ state of $^{24}$Mg at 26.3 MeV. The new $12^+$ state is discussed in the context of the collective and shell models.
