用共振散射法测量了α（12 C，α）12 C反应.用46、52、56和63 MeV的束流能量在16 O中11.6-22.9 MeV的激发能量范围内填充共振。在零度下测量弹性散射的角分布，使用在质量中心具有0-30的最小范围的分段硅条检测器的阵列。获得了14.1和18.5兆电子伏之间的8个共振的自旋，证实了在正常运动学中使用弹性散射的自旋分配。一个R-矩阵分析的数据进行，这表明，目前的理解16 O在这一地区是好的，但不完整。
A measurement of the α (12 C, α) 12 C reaction has been performed using resonant scattering with a gas target. Beam energies of 46, 52, 56 and 63 MeV were used to populate resonances in the excitation energy range of 11.6–22.9 MeV in 16 O. The angular distributions of the elastic scattering were measured at zero degrees, using an array of segmented silicon strip detectors with a minimum range of 0–30 in the centre-of-mass. The spins of 8 resonances between 14.1 and 18.5 MeV were obtained, confirming spin assignments made using elastic scattering in normal kinematics. An R-matrix analysis of the data was performed which indicates that the present understanding of 16 O in this region is good, but not complete.
