基于CDCC理论对氘核破裂效应进行初步研究(英文)

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。

Primary Research on Deuteron Breakup Effects with CDCC Theory

Based on the continuum discretized coupled channels (CDCC) theory,with the suitable initial values and boundary conditions,as well as the P3C5 algorithm to solve the coupled equations,a new code CDCCOM with higher calculation precision is written to observe the deuteron breakup effects on elastic scattering angular distributions and reaction cross sections.And the validity of this code is checked.By comparing with other theories and experimental data,it is found that the present work is valuable and applicable for large nuclei range below 200 MeV,and the code is feasible for studying the breakup effect on inelastic channels further.
