An upper limit (three standard deviations) of 8 x 10/sup -6/ has been determined for the branching ratio of gamma to particle decay of the 14/sup +/ resonance at E/sub c.m./ = 25.2 MeV in the /sup 12/C+/sup 12/C system. This limit is a factor of 2--3 lower than theoretically expected for an interpretation of the intermediate structure resonances as quasimolecular states in /sup 24/Mg, making this hypothesis unlikely. The experimental limit is consistent with an interpretation of these structures as shape resonances in a direct reaction process.
