Abstract

The 10 B+ 10 B reactions are measured with 50 and 72 MeV beams. The large spin of both beam and target nuclei (Jπ = 3 + ) is particularly suitable for the population of high spin states in the exit channels. Population and decay of different states in 12 C is studied through sequential decay reactions. The 12C excitation energy spectrum obtained from the 10B(10B, 8Be) reaction shows a number of both known and new states. In particular, a new state at Ex = 24.4MeV is observed to be strongly populated in the triple α-particle coincidences. The rarely seen state at Ex = 30.3 MeV is found to be strong in the d + 10 B decay channel, reinforcing the previous suggestions that it has the exotic 2α+2d molecular structure.
