The wavelength dependence of the two-photon ionisation of metastable D(2s) by a laser beam has been measured near the 2s ? 3p resonant frequency. A sharp structure is observed in the broad resonance profile at quite moderate intensity. Its origin is shown to be the spontaneous decay of the 3p state that competes with photoionisation. 相似文献
