摘要
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.
Theoretical and experimental investigation of resonance radiation trapping usually starts with the Holstein equation. In this paper we present a numerical quadrature method for our reduced solution to this equation. Demonstrative numerical calculation was carried out. The results agree with experimental data satisfactorily. The computation shows that our reduced solution and the corresponding numerical quadrature method are useful in handling rediation trapping problems.
