晕核^6He（25MeV／u）在^9Be上的弹性散射研究

Elastic Scattering of 6He from 9Be at 25 MeV/u

分析了北京大学核物理实验小组在日本RIKEN实验室完成的 25MeV/u6He和9Be的弹性散射实验数据, 得到了弹性散射微分截面角分布. 利用双折叠模型, 并通过拟合弹性散射微分截面得到了此弹靶体系在此能量下的弹性散射光学势.

We analyzed the ~6He elastic-scattering from ~9Be target at 25 MeV/u. A Center-of-Beam(CB) method was used to calibrate the particle-tracking detectors and set the reference system of the detection system. The double-folding model approach was used to calculate the real part of the optical model potential. The preliminary optical model potential parameters were extracted by fitting the experimental differential elastic-scattering cross-sections.
