基于<strong>HI-13</strong>串列加速器的核天体物理研究

Nuclear astrophysics research based on HI-13 tandem accelerator

中文摘要英文摘要

中国原子能科学研究院核天体物理研究组在HI-13串列加速器核物理国家实验室建成了我国首条低能放射性次级束流线,产生了从6He到22Na等11种放射性核束,利用这些放射性束流通过测量逆运动学转移反应开展了一系列核天体物理重要反应的研究,另外还通过厚靶实验方法和电荷交换反应开展了天体物理相关重要核结构信息的研究。在串列加速器Q3D磁谱仪上,利用稳定束测量了许多单核子转移和α基团转移的角分布,基于渐进归一化系数(Asymptotic Normalization Coefficient,ANC)或谱因子方法得到了一系列天体物理关键反应的天体物理S因子和反应率,为元素丰度、天体模型等相关研究提供了重要实验依据。

he first radioactive ion beam line, GIRAFFE, has been built at the CIAE HI-13 tandem accelerator in China. A total of eleven types of radioactive ion beam, including 6He, 7Be, and 8Li, have been generated. Several significant reactions in nuclear astrophysics have been indirectly measured via transfer reactions, and research on nuclear structure, relevant to nuclear astrophysics, has been performed using charge exchange reactions and thick-target experimental methods. A series of single nucleon or cluster transfer reactions have been measured using a Q3D magnetic spectrometer, and the astrophysical S-factors and reaction rates for essential reactions have been obtained. The obtained results serve as a crucial experimental foundation for research involving element abundance and celestial body models.
