Abstract

The unique opportunity presented by 10B + 10B reactions to study high-energy, high-spin states in the A=10 mass region is explored. Results from the measurement at 72 MeV are presented, the most important being new and rarely seen states in the 12C [1] and 13C [2], which motivate targeted future experiments. In particular, a new state of 12C at Ex = 24.4 MeV is strongly populated in the triple α-particle coincidences, while the rarely seen state at Ex = 30.3 MeV is found to be strong in the d+10B decay channel, reinforcing the previous suggestions that it has the exotic 2α+2d molecular structure [3]. Regarding the 13C nucleus, a potentially novel state at Ex = 19.0 MeV is prominently observed in α+ 9Be coincidences and demonstrates a well-defined cluster structure. Lastly, high-spin states in mirror nuclei pairs 9Be-9B, 10Be-10C and 11B-11C populated in the presented measurement are explored.
