根据/sup 12/C+/sup 236/U和/sup 16/O+/sup 232/Th反应的裂变碎片角分布，确定了复合核/sup 248/Cf的均方自旋值。各向异性，因此，平均平方自旋值比预期的大得多。再现亚势垒聚变激发函数中观察到的增强的模型不能解释自旋分布的观察结果。
The mean square spin value of the compound nucleus /sup 248/Cf has been determined from fission-fragment angular distributions for the /sup 12/C+/sup 236/U and /sup 16/O+/sup 232/Th reactions. The anisotropy and, hence, the mean square spin values are much larger than expected. Models which reproduce the enhancement observed in the sub-barrier fusion excitation functions fail to account for the spin-distribution observations.
