在二能级原子与激光衰波场相互作用的Schrodinger方程的解析解的基础上数值计算了原子反射率与原子入射角的依赖关系。计算结果表明,在正失谐情况下的原子反射率很高;但对于负失谐情形.当入射角小时,反射率较低;当入射角增大时,反射率先增加,然后经过一个峰值再下降;当入射角进一步增加时,反射率又急剧上升。这结果与光波在介质表面的反射率随入射角的增大单调上升有所不同.对此进行了一定的分析。

In a previous paper we have Obtained the exact solution for the reflection of twolevel atoms by an evanescent laser wave. In this peper we numerically calculate thedependence of reflection coefficient on the incidence angles a for the atom. We also compareour results with those of classical optics[7]. The comparison shows that there are somesimilarities while some difference exists. Finally some Physical explanations to the results aregiven.
