A simple model of above-threshold ionization which takes into account the processes of autoionization has been studied and the analytic solution of photoelectron spectra is presented. The effects of autoionization on abovethreshold ionization are discussed. It is shown that autoionization will make processes of above-threshold ionization more complicated and a lot of new effects will appear.

The experimental study of the relations between ｜ml｜ and field ionization thresholds of Stark components in Rydberg states of atomic cesium is reported. The three expressions of ionization thresholds of ｜ml｜=0，1,2 in atomic cesium are obtained completely from the same experiment.

Abstract The experimental study of the relations between |m_l| and field ionization thresho- lds of Stark components in Rydberg states of atomic cesium is reporte The threeexpressions of ionization thresholds of |m_l|=0,1, 2 in atomic cesium are obtainedcompletely from the same experiment.
