DESTRUCTION OF PEAK SWITCHING IN STRONG-FIELD AUTOIONIZATION PHOTOELECTRON SPECTRA
强场自电离光电子谱中峰开关效应的破坏

In this paper, the effect of the spatial inhomogeneity of the laser field and the size of detector acceptance angle or aperture on strong-field autoionization photoelectron spectra is investigated. It is shown that the photoelectron spectra are drastically affected by the above factors , for small detector acceptance angle or aperture size, peak switching appears in the photoelectron spectra, but for large detector acceptance angle or aperture size, peak switching is destroyed completely.
