Gamma radiation from the 16.1l-Mev state to the 9.63Mev state in C12 was identified with a three-crystal pair spectrometer and with 15 cm long by 12.7 diameter NaI(Tl) crystal detectors. The 6.45 plus or minus 0.05-Mev line occurs with a branching ratio of 1% of the well-known 11.67 to 4.43-Mev cascade radiation. The l6.ll-Mev state of Ci12 was obtained by bombardment of thick boron targets with protons at the 163-kev resonance for the B11 + p reaction. The yield of 6.45-Mev radiation showed resonance at the same energy as the cascade radiation. Coincidence spectra taken with two detectors, biased at 1.0 Mev, showed that less than 2.5% of the 6.45--Mev radiation is accompanied by gamma radiation, in agreement with the known alpha decay of the 9.63Mev state. The angular distribution of the 6.45-Mev radiation was measured. It is only consistent with a spin and parity of 3- for the 9.63-Mev state, when taken with the known alpha decay.
