摘要: Using a three-step laser saturation excitation technique, the saturation effects on the Ba 6pns (J=1) and 6pnd (J=1, 3) autoionization spectra are observed systemically in zero field. These saturation spectra are introduced to determine the high n members of 6pnl (l=0, 2) autoionizing series and are used to analyse the channel interactions among the autoionizing series in zero field. Furthermore, the saturation excitation technique is applied to the electric field case, in which the saturation spectra of Ba 6pnk (|M|=0, 1) autoionizing Stark states are measured. Most of these saturation spectra are observed for the first time so far as we know, which indicate the mixing of the autoionizing states in the electric fields.
