| Popis: | New data and preliminary results from an experimental study of the p + 11B reaction are presented. Using proton energies in the range of 167 – 170 keV the 2+ resonance in 12C at an excitation energy of 16.11 MeV was populated. Detecting the emitted a-particles in full kinematics allows us to study 12 C resonances and their properties. In addition to the 3-α break-up of the 16.11 MeV resonance we observe γ-transitions to lower lying resonances. Transitions to the 3− state at 9.64MeV, the 1− state at 10.84 MeV and the 1+ state at 12.71 MeV are clearly seen. The transitions to the 1− state has not been observed previously. In addition we see decays to structures of natural parity at excitation energies around 11-13 MeV. The results illustrate that the indirect detection of γ-decays is an effective technique for studying the low lying resonance spectrum of 12C. |
