The angular distribution for the inelastic scattering of 42-Mev alpha- particles by C/sup 12/, with excitation of the 7.65-Mev state, was measured. The experimental distribution shows maxima and minima consistent with 0+ or 2+ spin- parity assignment for the 7.65-Mev state, on an Austern, Butler, McManus type of direct interaction theory. A search was made for coincidences between the inelastically scattered alpha particles and recoil carbon nuclei in an attempt to determine the probability that the 7.85-Mev stute decays by transitions to the ground state of C/sup 12/. It was found that there is less than one chance in ten that this probability exceeds 0.1%. This low probability is not inconsistent with current theories of helium burning in stars and provides additional support for the usual 0+ assignment for the 7.65-Mev state. (auth)
