铷原子初通道─末通道辐射跃迁矩阵元研究

RADIATIVE TRANSITION OF Rb ATOM BETWEEN INITIAL AND FINAL CHANNELS

在相对论性自洽场理论基础上，把量子亏损理论的一个初态到一个末通道的跃迁过程进行了推广：具有相同角动量特征的初态形成所谓的初通道，通过定义重整化矩阵元，统一处理了一个初通道激发到一个末通道的无数个光跃迁过程．作为例子，计算了你原子＂Ｓ＿１／２－Ｐ１／２＂，Ｐ＿１／２－ｄ＿３／２，ｄ＿３／２－ｆ＿５／２通道之间的光吸收过程．

As an extension of theoretical study of transition from an initial state to a final channel,the initial states with same angular momentum form varied initial channels. By defining anew renormalized matrix element, the atomic radiative processes from an initial channel to afinal channel can be treated in an unified manner. As an example, we present here the renor-malized matrix element of Rb atom between initial and final channels.
