计算了超冷原子入射到倏逝波原子镜上的反射几率，分析了观察量子反射的最佳条件。我们发现，平均超过高斯分布的激光束显着降低了量子签名，并考虑了一个适当的光圈，限制光束强度的变化的影响。我们表明，量子反射是特别敏感的原子表面电位的细节，并可用于解决延迟效应。@S1050-2947 ~97！50611-1#
We calculate the reflection probability for ultracold atoms incident on an evanescent-wave atomic mirror, and analyze the optimum conditions to observe quantum reflection. We find that averaging over the Gaussian profile of the laser beam dramatically reduces the quantum signature, and consider the effects of an appropriate aperture that limits the variation of beam intensity. We show that quantum reflection is particularly sensitive to details of the atom-surface potential, and could be used to resolve retardation effects. @S1050-2947 ~97!50611-1#
