摘　　要：利用鞍点复转动的方法,计算了21个位于BeⅡ的11S和21P阈值之间的2P0自电离态,得到了包括相对论修正和质量极化修正在内的共振能量和宽度。对于23S阈值之上的共振态,我们将BeⅡ的结果与LiⅠ的结果作了对照。We calculate the positions and the widths of 21 2P 0 resonances in BeⅡ between 1 1S 0 and 2 1P thresholds with a saddle point complex rotation method. Relativistic and mass polarization corrections to the autoionization energy are included. For the rgeion above 2 3S , our present results of BeⅡ are compared with that of LiⅠ. The dependence of the widths on the atomic number is discussed.
