We review an extensive study of the beryllium isotopic chain carried out at RIKEN. In particular, we discuss the results on \(^{13,15}\hbox {Be}\), two key isotopes for the understanding of dineutron configurations and decays in \(^{14,16}\hbox {Be}\). In the \(^{13}\)Be case, a detailed analysis of its spectroscopy, including for the first time a well-founded reaction framework and a realistic three-body model of \(^{14}\hbox {Be}\) that incorporates core excitations, confirms the dominant \(\ell =1\) content of the low-lying spectrum. In the \(^{15}\)Be case, the fragmentation of \(^{18}\)C, a priori free of any selection rules that may have precluded the observation of states in previous experiments, has confirmed the only known state at about 1.8 MeV, assigned according to shell-model calculations to a spin-parity \(5/2^+\). Some perspectives of these studies are also given.

我们回顾了在RIKEN进行的铍同位素链的广泛研究。特别是，我们讨论了\（^ {13,15} \ hbox {Be} \）上的结果，这是了解\（^ {14,16} \ hbox {Be} \ ）。在\（^ {13} \） Be情况下，对其光谱进行了详细的分析，包括首次建立了有充分根据的反应框架和现实的\（^ {14} \ hbox {Be}三体模型包含核心激励的\）确认了低频谱的主要\（\ ell = 1 \）含量。在\（^ {15} \）情况下，\（^ {18} \）的碎片C，没有任何可能会排除先前实验中观察状态的选择规则的先验条件，已经确认了大约1.8 MeV的唯一已知状态，根据壳模型计算将其分配给自旋奇偶性\（5/2 ^ + \）。还给出了这些研究的一些观点。
