[en] Recent studies of the ¹²C(¹⁶O,α)²⁴Mg reaction at E(¹⁶O) = 145 Mev have revealed the existence of several broad states with E sub(X)(²⁴Mg) = 20 to 60 MeV. The energies of these states have been taken as evidence that they are members of the ¹²C + ¹²C molecular band J sup(π) = (10⁺) through J sup(π) = (18⁺). Subsequent investigation of the properties of these states, however, has failed to reveal the expected partial width for ²⁴Mg* → ¹²C + ¹²C. It is shown that these states can be interpreted as an extension of the ²⁴Mg Yrast sequence which is populated by the well understood high spin selectivity of α particle evaporation from a ²⁸Si compound nucleus.
