Ionization energies for Rydberg $^{4} He$ ( $1 s n p^{1, 3} P$ ) states using the correlated B-spline basis function method

Jing Chi, Hao Fang, Yong-Hui Zhang +2

We extend the correlated B-spline basis function (C-BSBF) method to high-precision calculations of the ionization energies of helium Rydberg $n^{1, 3} P$ states ( $n = 24$ -- $35$ ). Using…

Precise ab initio calculations of $^{4}$ He( $1 s n p^{3} P_{J}$ ) fine structure of high Rydberg states

Hao Fang, Jing Chi, Xiao-Qiu Qi +3

High-precision measurements of the fine-structure splittings in helium high Rydberg states have been reported, yet corresponding ab initio benchmarks for direct comparison remain u…

A Simple approach for precision calculation of Bethe logarithm

San-Jiang Yang, Jing Chi, Wan-Ping Zhou +4

In this article we propose a simple approach for the precision calculation of Bethe logarithm. The leading contributions are obtained using specific operators, while the remaining…
