摘要：

Photoelectron energy spectra from multiphoton ionization of magnesium reveal that direct nine or ten-photon transitions to 4p and possibly 5p thresholds are taking place around 586 nm and about 1012W cm−2. Lineshapes indicate that such transitions are enhanced by the intermediate four-photon resonance with the 3p21S two-electron state, above the ionization threshold. © 1990 IOP Publishing Ltd.
