摘要：

We report an experiment in xenon which confirms theoretical predictions [Payne et al., Phys. Rev. A 48, 2334 (1993)] on the pressure dependent suppression of the ac Stark shifting of even-photon resonances. In the copropagating configuration the ac Stark shift introduced by a second laser is totally suppressed at elevated concentrations due to a very complete destructive interference between two pumping pathways. The ac Stark shift persists in the counterpropagating configuration.
