摘　　要：采用多通道鞍点和鞍点复数转动方法，计算了类锂离子（Ｚ＝３—１０）２ｓ２ｓ２ｐ２Ｐ０和２ｓ２ｐ２ｐ２Ｄ三激发共振态系列的能量、精细结构和寿命．Ａｕｇｅｒ宽度由耦合主要的通道得到，相对论效应计算到一级微扰，质量极化效应计算到无穷级．Abstract  The energies , fine structures and lifetimes of the 2s2s2p 2P 0 and 2s2p2p 2D triply excited states of the Li isoelectronic sequence are calculated using multichannel saddle point and saddle point complex rotation methods. A restricted variational method is used to extrapolate a better nonrelativistic energy. The relativistic corrections are calculated with first order perturbation theory. The shifts and widths are studied with one open channel at a time as well as fully coupled open channels. The radiative transition rates and the fine structure splittings for the 2P 0 and 2D states are also calculated. These results are compared with the existing theoretical and experimental data in the literature.
