© 2025 The Author(s)The structure of 11B was investigated at Legnaro National Laboratories of INFN using the 6Li(6Li,p?) fusion-evaporation reaction. Emitted protons feeding excited states of 11B were detected by the GALTRACE silicon telescopes in coincidence with ? rays measured by the GALILEO HPGe array. The level and ?-decay scheme of 11B was reconstructed on an even-by-event basis by combining particle and ?-ray spectroscopy techniques. In particular, the ? decay from the possible near-threshold proton resonance was searched for, providing first results on its ?-ray branch with a 5? and 3? confidence level. Results are discussed along with predictions of the Shell Model Embedded in the Continuum (SMEC).
