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.

Abstract The purpose of this paper is to propose a theoretical treatment of radiation trapping in a multiple lines coupled system in which coupling includes collisional energy transfer and cross absorption between the excited states. First, to describe the coupled system, the Holstein equation of radiation trapping is extended to an integral differential master equation group in which the vector and matrix form is adopted. Then by use of operator manipulations, the asymptotic solution in the form of a series expansion in terms of operators is presented. Finally, the asymptotic solution is reduced, leading to a result which can not only give the system a complete description, but also has far more advantages than the simple cut off solution. A numeral illustration of a two excited states system is also presented.

提出一种处理多荧光谱线耦合系统辐射束缚问题的理论方法.这里的耦合包括激发态间的碰撞传能和当谱线重叠时对荧光的交叉吸收.首先将描述辐射束缚的Holstein方程扩展为适用于描述多个激发能级且包括交叉耦合项的微分积分方程组,并将其纳入矢量、矩阵的形式.然后直接通过算符运算求解,给出按算符展开的级数解式.最后对级数解进行约化,导出一个只用有限项便可对系统行为进行完整描述的、远较简单截断近似优越的结果.还给出了一个双激发能级系统的计算实例
