共振辐射束缚的理论和实验研究大都从Holstein方程出发.本文基于我们提出的Holstein方程约化解,设计出相应的数值积分计算方案.该方案的计算结果与实验结果能较好地吻合;与Holstein方程的本征函数展开解及时间级数展开解相比较,该方案具有能够给出体系完整的时间行为,计算收敛速度快等优点.计算结果表明,Holstein方程的约化解及其数值积分的计算方法是处理辐射束缚的有效途径.
The theoretical and experimental researches on the restraint of resonance radiation mostly start from the Holstein equation. Based on our approximate solution to the Holstein equation, a numerical scheme for numerical integration is designed. The calculated results agree well with the experimental results. Compared with the eigenfunction expansions and the time series expansions, this scheme has the advantages of being able to give the complete time behavior of the system and the fast convergence of the computational results. The calculation results show that the approximate solution of the Holstein equation and its numerical integration method Is an effective way to deal with radiation constraints.
