摘要

摘要

En 中文
dineutron是一种空间上紧凑的双中子簇，预计会出现在原子核的低密度部分。近年来，关于dineutron簇的实验和理论研究取得了快速进展，特别是在丰中子稀有同位素方面。实验上，通过库仑碎裂、电荷半径测量和准自由质子散射，已经获得了在双中子晕核（如$$^{11}$$ Li）中dineutron的证据。刚刚超出中子滴线的特定不束缚核，通过发射两个中子而衰变，也是具有dineutron关联的候选体。例如，最近对$$^{16}$$ Be的dineutron结构进行了研究，重点关注其衰变到核心和两个中子。理论上，研究表明dineutron部分归因于两个价中子的不同宇称构型的混合。包括衰变过程动力学效应的少体理论，在解释三体衰变中发挥着重要作用。我们还讨论了四中子簇，展示了最近的四中子实验结果和$$^{28}$$ O的观测。这些态与dineutron关联的可能相关性进行了讨论。最后，我们讨论了丰中子核中dineutron簇的未来展望及其与少体物理学中普适特征的关系。
