摘要

应用被动核径迹法(NTM)研究了7Li+Pb在~ 31 MeV下的带电粒子反应产物。这是对8pLP项目(LNL-INFN-Italy)的贡献,在该项目中,我们展示了一种通过PADC检测从反应碎片中记录带电粒子的替代方法。主要优点是被动系统集成了整个实验的数据,对于低速率反应过程具有重要意义。通过轨迹形状分析确定了反应产物和散射束粒子。由于需要先验知识来关联从目标中出现的每种类型的粒子给出的轨迹尺寸分布,因此NTM固有的一些局限性。结果表明,该技术在较大范围的粒子类型的反应数据解释中提供了有用的信息。

PADC-NTM Applied in 7Li+Pb at 31 MeV Reaction Products Study
Passive nuclear track methodology (NTM) is applied to study charged particles products of the reaction 7Li+Pb at ~ 31 MeV. It is a contribution to the 8pLP Project (LNL-INFN-Italy) in where we show an alternative approach to register charged particle from reaction fragments by PADC detection. The main advantage is that the passive system integrates data over the whole experiment and has its importance for low rate reaction processes. Reaction products as well as scattered beam particles are determined from track shape analysis. Some limitations are inherent to NTM since a priori knowledge is required to correlate track size distribution given by each type of particle emerging from the target. Results show that the passive technique gives useful information when applied in reaction data interpretation for a relatively large range of particle types.
