摘　　要：:计算了处在粒子数态的单模量子场与二能级原子相互作用时能级ACStark移动 ,平均能级移动值随场模波频率变化呈色散线型 ,随场模中光子数的增加会逐渐达到饱和。另外 ,还发现即使是场模中光子数为零 。WT5BZ]AC-Stark level shifts of two-level atom are calculated when quantized field in number state interacts with atom. The timeaveraged level shifts display the dispersion shape with the change of frequency of field mode and can reach saturation with the increase of photon number in field mode. In addition, it is also found that quantized field can still shift atomic level even if the photon number in field equals zero. [WT5HZ]
