中子诱发d产物的微分反应截面的测量

Measurement of Differential Cross Sections of Neutron-induced d

摘要: 在中国散裂中子源反角白光中子源，测量了12个中子能量点\rm^12C(n,d)x的角微分反应截面。利用轻带电粒子探测器阵列(LPDA) ΔE-E 望远镜系统，测量了在实验室坐标系下从24.5°到155.5° \rm^12C(n,d)x 的角微分反应截面。实验结果能够很好地符合以前的实验结果。由于缺少实验数据，这项工作为相关数据库的评价及数据库研制提供了重要参考。

Abstract: The angle-differential cross sections of neutron-induced d production from carbon were measured at 12 neutron energies at Back-n white neutron source of China Spallation Neutron Source (CSNS). By employing the \varDeltaE-E telescopes of the Light-charged Particle Detector Array (LPDA) system from 24.5^\circ to 155.5^\circ in the laboratory system, the angle-differential cross sections of the ^12\rm C(\rmn,\rmd)x reactions were measured. The experimental results are in good agreement with the previous ones. The present work can provide a reference to the data library considering the lack of experimental data.
