为研究氘核的破裂效应对弹性散射角分布和反应截面的影响,基于连续离散化耦合道(CDCC)理论编制了程序CDCCOM。从中心点波函数的初始值出发,利用P3C5算法求解耦合道方程组,进而通过边界点上内、外区的波函数相匹配求得S矩阵元。P3C5算法提高了计算精度,同时验证了程序CDCCOM的有效性。通过与其他工作的计算结果及实验数据进行比较,认为在氘核入射能量低于200 MeV的情况下,对于大多数靶核,通过CDCCOM都能够得出合理的结果,表明该程序可用于进一步研究氘核诱发的非弹性核反应。
In order to study the effect of the deuteron rupture on the elastic scattering angle distribution and the cross section of the reaction, a program CDCCOM was developed based on the theory of continuous discrete coupled channel (CDCC). Starting from the initial value of the central point wave function, the coupling equations are solved by using the P3C5 algorithm, and the S matrix elements are obtained by matching the wave functions of the inner and outer regions at the boundary point. The P3C5 algorithm improves the calculation accuracy and verifies the validity of the program CDCCOM. Comparing with other work’s calculation and experimental data, it is considered that CDCCOM can give reasonable results for most target nuclei when the incident energy of deuteron is less than 200 MeV, which indicates that the program can be used for further research Deuteron induced non-elastic nuclear reaction.
