Investigating the structure of 11B using particle-γ coincidences
The structure of 11 B was investigated at Legnaro National Laboratories of INFN using the 6 Li( 6 Li,p γ ) fusion-evaporation reaction. Emitted protons feeding excited states of 11 B were detected by the GALTRACE silicon telescopes in coincidence with γ rays measured by the GALILEO HPGe array. The level and γ -decay scheme of 11 B was reconstructed on an even-by-event basis by combining particle and γ -ray spectroscopy techniques. In particular, the γ decay from the possible near-threshold proton resonance was searched for, providing first results on its γ -ray branch with a 5 σ and 3 σ confidence level. Results are discussed along with predictions of the Shell Model Embedded in the Continuum (SMEC).
