Angular Distribution of Gamma-Rays and Short-Range Alpha-Particles fromN15(p, αγ)C12

Measurements of the angular distributions of gamma-rays and alpha-particles from the reaction ${\mathrm{N}}^{15}(p, \alpha \gamma ){\mathrm{C}}^{12}$ indicate that the 4.432-Mev excited state of ${\mathrm{C}}^{12}$ is $2^{+}$ or >4, that the 12.51-Mev level of ${\mathrm{O}}^{16}$ is $2^{-}$ or >5, that the 12.95-Mev level is $2^{-}$ or >5, and that the 13.24-Mev level is $4^{+}$ or >5.
