B10+B10 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 C12 are studied through sequential decay reactions. The C12 excitation energy spectrum obtained from the B10(B10,Be8) 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=30.3MeV is found to be strong in the d+B10 decay channel, reinforcing the previous suggestions that it has the exotic 2α+2d molecular structure.

Abstract
B10+B10 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 C12 are studied through sequential decay reactions. The C12 excitation energy spectrum obtained from the B10(B10,Be8) 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=30.3MeV is found to be strong in the d+B10 decay channel, reinforcing the previous suggestions that it has the exotic 2α+2d molecular structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
