DISTORTED-WAVE CALCULATIONS OF THE RESONANCE EXCITATION DOUBLE AUTOIONIZATION CROSS SECTIONS FOR THE Li ISOELECTRONIC SEQUENCE
类Li等电子系离子共振俘获双自电离截面的扭曲波计算

A distorted -wave Born exchange (DWBE) approximation is used to calculate the resonance-ex-citation double autoionization (REDA) for the Li Isoelectronic sequence.Comparison shows good a-greement 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.
