W $^{15+}$和W $^{16+}$电子碰撞单电离的混合子组态平均和能级畸变波处理
Hybrid subconfiguration-average and level-to-level distorted-wave treatment of electron-impact single ionisation of W$^{15+}$ and W$^{16+}$
摘要：
最近，我们已经证明了（Jin et al. 2020，J. Phys. B：At.摩尔Opt.Phys.53，075201），W $^{14+}$离子的电子碰撞单电离（EISI）的混合子构型平均和水平到水平扭曲波处理代表用于计算复杂离子的EISI截面的准确和可管理的方法。在这里，我们通过将W $^{15+}$和W $^{16+}$的EISI的混合横截面与Schury等人2020，J. Phys. B：At.摩尔53，015201）。我们的计算还考虑了共振激发双自电离（REDA）过程，这是重要的电子能量范围370-600 eV和可能存在的初始亚稳离子在实验中。
英文摘要：
Recently, we have demonstrated (Jin et al. 2020, J. Phys. B: At. Mol. Opt. Phys. 53, 075201) that a hybrid subconfiguration-average and level-to-level distorted wave treatment of electron-impact single ionisation (EISI) of W$^{14+}$ ions represents an accurate and manageable approach for the calculation of EISI cross sections of a complex ion. Here we demonstrate the more general validity of this approach by comparing hybrid cross sections for EISI of W$^{15+}$ and W$^{16+}$ with the recent experimental results of Schury et al. 2020, J. Phys. B: At. Mol. Opt. Phys. 53, 015201). Our calculations also account for the resonant-excitation double autoionisation (REDA) process which is important in the electron energy range 370-600 eV and for the possible presence of initially metastable ions in the experiment.
