Phys. Rev. Lett. 63, 1058–1061 (1989)Resonantly enhanced above-threshold ionization of heliumReceived 10 March 1989; published in the issue dated 4 September 1989 The role of multiphoton resonances in the above-threshold ionization of helium at intensities above 1014 W/cm-2 is investigated by both theory and experiment from 280 to 297 nm. Strong enhancement is observed in above-threshold ionization electron spectra and is attributed to five- and six-photon resonances to the 1s2p and 1s3d, respectively. Numerical solution of the time-dependent Schrödinger equation predicts asymmetric resonance profiles with positions and ionization rates which are in good agreement with experiment. © 1989 The American Physical Society URL:
