Different aspects of nuclear structure and reaction mechanisms in the collision 13N+11B Original Research Article

The reaction 13N+11B has been investigated at two 13N 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 BaFView the MathML source scintillators, respectively. Several reaction channels have been analysed with different aims. The proton transfer reaction 11B(13N, 12C)12C to various excited states of 12C has been studied to obtain information on the 13NView the MathML source structure. The excitation energy of the 24Mg compound nucleus was in the region where several resonances occur in the 12C+12C system. The six-α decay of the 24Mg intermediate system has been studied. Some of these events have been identified as coming from the break-up of two 12C∗ in the 3View the MathML source–3View the MathML source and 3View the MathML source–0View the MathML source states. The total fusion cross section has also been extracted from the data. In order to extract information on the isospin purity/mixing in 24Mg at high excitation energy (View the MathML source MeV), the GDR γ emission from this self-conjugate nucleus has been studied. A comparison of γ spectra has been undertaken for the reactions 13N+11B and 14N+10B.
