Abstract

Photoionization of neutral chlorine atom is investigated in this paper in the framework of the screening constant per unit nuclear charge (SCUNC) method. Resonance energies, quantum defects and effective charges of the 3s23p4 (3P2,1,0)ns and 3s23p4 (3P1,0)nd Rydberg series originating from both the 2P03/2 ground state and the 2P01/2 excited state of chlorine atom are reported. The present study believed to be the first theoretical investigation is compared with the recent experimental measurements (Yang et al., Astrophys. J. 810:132, 2015). Good agreements are obtained between theory and experiments. New SCUNC data are tabulated as useful references for interpreting astrophysical spectra from neutral atomic chlorine.

中性氯原子的光电离研究

本文在单位核电荷筛选常数(SCUNC)方法的框架下研究了中性氯原子的光离。本文报道了分别来自氯原子2P03/2基态和2P01/2激发态的3s23p4 (3P2,1,0)ns和3s23p4 (3P1,0)和Rydberg系列的共振能、量子缺陷和有效电荷。本研究被认为是第一次理论研究，并与最近的实验测量进行了比较(Yang et al.， Astrophys.)。[j] .中文信息学报，2015)。理论与实验结果吻合较好。新的SCUNC数据被制成表格，作为解释中性原子氯的天体物理光谱的有用参考。

期刊介绍： Atoms (ISSN 2218-2004) is an international and cross-disciplinary scholarly journal of scientific studies related to all aspects of the atom. It publishes reviews, regular research papers, and communications; there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. There are, in addition, unique features of this journal: -manuscripts regarding research proposals and research ideas will be particularly welcomed. -computed data, program listings, and files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Scopes: -experimental and theoretical atomic, molecular, and nuclear physics, chemical physics -the study of atoms, molecules, nuclei and their interactions and constituents (protons, neutrons, and electrons) -quantum theory, applications and foundations -microparticles, clusters -exotic systems (muons, quarks, anti-matter) -atomic, molecular, and nuclear spectroscopy and collisions -nuclear energy (fusion and fission), radioactive decay -nuclear magnetic resonance (NMR) and electron spin resonance (ESR), hyperfine interactions -orbitals, valence and bonding behavior -atomic and molecular properties (energy levels, radiative properties, magnetic moments, collisional data) and photon interactions
