摘要

利用6Li（6Li,pγ）的熔融蒸发反应，研究了11B的结构。发射的质子进入11B的激发态被GALTRACE硅望远镜探测到，与伽利略HPGe阵列测量到的γ射线一致。结合粒子能谱和γ射线能谱技术，在单事件基础上重建了11B的能级和γ衰变模式。特别是，从可能的近阈值质子共振中寻找γ衰变，在其γ射线分支上提供了第一个具有5σ和3σ置信水平的结果。对结果进行了讨论，并对连续统内嵌壳模型（SMEC）进行了预测。

Investigating the structure of 11B using particle-γ coincidences

The structure of ¹¹B was investigated at Legnaro National Laboratories of INFN using the ⁶Li(⁶Li,pγ) fusion-evaporation reaction. Emitted protons feeding excited states of ¹¹B 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 ¹¹B 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 5σ and 3σ confidence level. Results are discussed along with predictions of the Shell Model Embedded in the Continuum (SMEC).
