Anomalously broad spin distributions in sub-barrier fusion reactions

Technical Report ·
OSTI ID:6417381
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. 12 refs., 3 figs.
