摘要
在 CERN 的 ISOLDE 设施中，利用 ISOLDE 衰变站（IDS）装置测量了 Mg 衰变中的 延迟质子与 发射。现有的衰变纲图得到了更新，特别是关于向 Ne 激发态的质子跃迁部分。谱中多个部分的干涉特征被用于确定 Na 高激发态的自旋与宇称。先前报道的 p 分支得到了确认。提取出 Mg 的半衰期为 120.5(4) ms。修正后的衰变纲图被用于检验衰变中的镜像对称性，并提取了 Mg 的 强度分布以与理论进行比较。

14 pages, 10 figures. This version includes the same content as the published, open-access version. In this version, details about the conditions during the experiment have been expanded (section 2), scattered claims and comments have been clarified and columns containing particle (lab) energies have been added to tables 1 and 2
