摘要 利用基于多组态Driac-Fock(MCDF)理论方法发展的程序包GRASP及FAC程序包,详细计算了共振双激发态1s2l2l′的共振能量、自电离速率、辐射速率及双电子复合截面.重点讨论了Breit相互作用对类氦钨离子双电子复合截面的影响. By using the program package of GRASP and FAC which are based on the multiconfiguration Dirac-Fack method,the resonant energy,radiative decay rates,autoionization rates of the doubly excited states 1s2lsl′and the corresponding dielectronic recombination(DR)cross sections have been calculated for He-like tungsten ions.It focuses on the influence of the Breit interaction on the DR cross sections.
