使用RIKEN的RIBF的SAMURAI光谱仪进行未结合核C的光谱分析。在C +n系统中观察到6个共振态，其相对能量分别为0.52，0.77，1.36，1.91，2.22和3.20 MeV。考虑到C碎片的符合射线态，我们推导出共振态的激发能分别为= 3.02，1.51，3.86，2.65，4.72和3.94 MeV。通过将平行动量分布与理论预测进行比较，确定了在=2.65和3.94 MeV的两个观测态的轨道角动量为1。
Spectroscopy of an unbound nucleusC was performed using the SAMURAI spectrometer at RIBF of RIKEN. Six resonances were observed for theC+n system with relative energies of 0.52, 0.77, 1.36, 1.91, 2.22 and 3.20 MeV. The excitation energies () of the observed resonances were deduced, by taking into account the states of theC fragments identified by coincidentrays, as=(3.02), 1.51, (3.86), 2.65, (4.72) and 3.94 MeV. The orbital angular momenta of the two observed states inC at=2.65 and 3.94 MeV were determined as 1 by comparing parallel momentum distributions with theoretical predictions.
