Study on Structure of Unstable Nuclei through Breakup and Knockout Reactions at Intermediate and High Energies

中高能区的破碎和敲出反应,由于机制相对简单、对核的表面敏感、理论处理比较成熟等原因,在非稳定核的晕结构、壳移动等奇特性质研究中发挥了独到作用.针对次级束流强度较弱、能散较大等特点,实验上发展和应用了逆运动学有效立体角完全测量、轻重靶结合、高精度消色差磁谱仪、前向中子谱仪、在束7测量等技术手段,大大提升了实验的探测能力和选择性.从物理问题探索和实验路线演变的角度,回顾了非稳定核破碎和敲出反应的发展过程与启示,并探讨未来的走向.
