摘　　要：采用三步孤立实激发与偏振光激发相结合的技术将 Ba原子分别从中间态6snp1 D2 (n=7～ 41 )和 6snp3D2 (n=7～ 2 9)激发到 6p1 / 2 nd以及 6p3/ 2 nd自电离态 ,从而获得了这 4个系列的自电离光谱。采用 Lorentz线型拟和的方法对这The Ba 6p n d autoionizing states have been systematically studied using a three step ICE approach combined with the polearized excitation technique. The 6p n d( J =1,2) autoionizing spectra with n =7～41 excited from 6s n p 1D 2 and with n =7～29 excited from 6s n p 3D 2 have been measured, and the different spectroscopic properities between the 6p 1/2 n d and 6p 3/2 n d series have been detailed discussed by fitting the experimental spectra to signal and multi Lorentz profiles, respectively.
