Abstract

The reaction N+B has been investigated at two N beam energies: 29.5 and 45 MeV. Charged particles and γ rays emitted in the reactions have been detected using a large array of silicon strip detectors and BaF scintillators, respectively. Several reaction channels have been analysed with different aims. The proton transfer reaction B(N, C)C to various excited states of C has been studied to obtain information on the N structure. The excitation energy of the Mg compound nucleus was in the region where several resonances occur in the C+C system. The six-α decay of the Mg intermediate system has been studied. Some of these events have been identified as coming from the break-up of two C in the 3-3 and 3-0 states. The total fusion cross section has also been extracted from the data. In order to extract information on the isospin purity/mixing in Mg at high excitation energy (E∼47 MeV), the GDR γ emission from this self-conjugate nucleus has been studied. A comparison of γ spectra has been undertaken for the reactions N+B and N+B.
