Abstract
The singlet S-wave resonances of the He atom embedded in dense quantum plasmas are investigated by applying the complex-coordinate rotation method. The modified Debye–Hückel potential is used to model the effective interactions of the test atom in a dense quantum plasma environment. The explicitly correlated Hylleraas configuration-interaction basis function is employed to take into account the electron correlation effect. The first ten S-wave resonance states of the He atom below the N = 2 thresholds of the He+ ion are calculated, and the resonance energies and widths at a variety of screening parameters are obtained with high accuracy. The plasma screening effect on the expectation values of the radial and angular physical quantities are analyzed for the first time.
应用复坐标旋转方法研究了嵌入致密量子等离子体中的氦原子的单S波共振。修正的 Debye-Hückel 势用于模拟高密度量子等离子体环境中测试原子的有效相互作用。为了考虑电子相关效应，采用了显式相关的 Hylleraas 配置-相互作用基函数。计算了 He+ 离子 N = 2 阈值以下 He 原子的前十个 S 波共振态，并高精度地获得了各种屏蔽参数下的共振能量和宽度。首次分析了等离子体屏蔽对径向和角度物理量期望值的影响。
