| 中文摘要 | strong laser-field-induced autoionisation in the presence of both photoionising and radiative decay of the autoionising state (as) is investigated, focusing on the laser intensity dependence of the photoemission and photoelectron spectra. in contrast to previous predictions, power broadening and increasing reduction of the doublet peak heights with field strength are found in the photoemission spectrum. similar effects leading to considerable suppression and even complete disappearance of the lowest-order peaks in the photoelectron spectrum, together with peak switching, are also demonstrated, which are closely related to above-threshold ionisation. in addition, it is suggested that the total number of energetic photoelectrons may serve as an alternative to measuring the atomic parameters of the as. all these effects are attributed to the presence of the strong `probe': laser-induced decay of the as. |
