利用R矩阵理论程序,采用数值计算方法,通过拟合实验测量的中重核激发函数,确定光学模型势,提取共振态的共振能量、衰变宽度等.计算了共振弹性散射激发态的谱因子,并和其它实验提取的谱因子数据进行了比较,得到了和实验一致的结果.此方法将来可以推广到轻核以及非束缚核的研究中去.
In this article, the experimental excitation function has been simulated in the numerical method based on R matrix theory and optical model potential, the decay energy and decay partial width of the resonant states have been obtained. Then the spectroscopic factor of the excited state in resonance elastic scattering reaction has been calculated, and it was compared with other experimental results, it shows a good agreement with the experimental data.
