Abstract
By analyzing the phase of transition probability amplitude,a formula for level shift induced by the time-dependent perturbation of quantum transition is given.AC-Stark shifts of the levels in two-level atoms are calculated,which are induced by mono-mode quantized field.The calculated results indicate that the quantum statistic property can directly influence the atomic level shift.
