DISTORTED\|WAVE CALCULATIONS OF THE RESONANCE EXCITATION DOUBLE AUTOIONIZATION CROSS SECTIONS FOR THE Li ISOELECTRONIC SEQUENCE 

利用扭曲波玻恩交换（ Ｄ Ｗ Ｂ Ｅ） 近似方法计算了类锂等电子系离子的共振俘获双自电离（ Ｒ Ｅ Ｄ Ａ） 截面，计算结果同实验和其他理论相一致．还重点研究了组态混合和辐射通道对 Ｒ Ｅ Ｄ Ａ 过程的影响以及 Ｒ Ｅ Ｄ Ａ 在总截面中的贡献大小，并给出了随 Ｚ 的变化趋势．

A distorted\|wave Born exchange (DWBE) approximation is used to calculate the resonance\|excitation double autoionization (REDA) for the Li Isoelectronic sequence.Comparison shows good agreement between the present calculation and experimental data and other theoretical results.In this paper,our research is focused on the effect of the configuration\|mixing and radiation channel on the REDA,and the REDA contribution to the ionization process.Also their variation with ion charge Z is given.
