丰中子核⁶He在²⁸Si靶上的反应总截面测量

摘要: 实验测量了20—40MeV u的轻丰中子核⁶He在Si靶上的反应总截面,并且结合⁶He的高能实验数据,采用双参数HO密度分布形式用Glauber模型计算得到较好的拟合.与Warner的实验数据比较,反应总截面数据系统性好,并与能量有明显的依赖关系. Total reaction cross section (σt) was measured for neutonrich nuclei ⁶He on ²⁸Si target from about 20 to 40 MeV/u and compared with Warner s experimental data. It is found that the total cross section of ⁶He on ²⁸Si depends on the energy and it can be fitted well by Glauber model using twoterm HO density distribution from high energy data of ⁶He.
