Popis: A study of the [sup 12]C([sup 12]C, 3[alpha])[sup 12]C reaction has been performed in order to determine the magnitude of the process by which the 7.65 MeV, 0[sub 2][sup +], state in [sup 12]C breaks up directly into three alpha particles, in contrast to the sequential decay through [sup 8]Be. The strength of this decay channel has important implications for the production rate of [sup 12]C in stellar nucleosynthesis. The present measurement indicates that the contribution of this decay process to the alpha width, [Gamma][sub [alpha]], of this state is less than 4%.
