摘要: 建议在兰州放射性束流线( R I B L L)上建设3 套装置: 直接反应精细测量装置, 用来对放射性束的粒子的运动轨迹逐一进行跟踪, 以及对粒子的电荷态、核电荷数、质量数和能量进行精确跟踪, 从而得到核反应和核结构的准确信息; 磁谱探测系统, 它是由一个二极磁铁和相关真空室组成, 一方面它是一个谱仪系统, 用来分离原始放射性主束和次级反应产物, 进行粒子种类和能量的测量, 另一方面, 还可以用来研究放射性核的电磁矩和基态组态; 奇异衰变的4π探测装置是由5套大面积位置灵敏薄片硅探测器和 Cs I( Tl)组成的望远镜组, 可覆盖整个探测空间的60% ~70% ,外加多个塑料中子探测器或 γ探测器, 用来测量奇异核和蒸发余核的关联粒子发射, 寻找和测量奇异的放射性衰变.Radioactive Ion Beam Line in Lanzhou (RIBLL) is able to produce hundreds of radioactive ion beams, by mean of projectile fragmentation.
