摘要
在组态相互作用模型的基础上对Be2+等二电子系列基态电子关联能的计算方法进行了研究,利用变分原理,采用B样条处理径向基,用“混合L”法处理角向基,给出He,H-,Li+,Be2+,B3+等5种原子(离子)系列的有关计算结果,并与其它理论方法计算的结果作了对比,显示出B样条方法优越的计算能力.
We report the investigation on calculation methods of ground state correlation energy of double electron system atoms (or ions) by using B splines basic sets. These methods are part of application category of calculas of variations, and adopt B splines techniques to deal with the radial bases, and at the same time, deal with the angular bases by using Goldman′s mixed L method. We give calculation results of He, H -, Li +, Be 2+ , B 3+ atoms (or ions), and compare these results with others′ theoratical methods. This comparison demonstrates that our calculation methods have excellent computing accuracy and efficiency.
