For example, chromium (Cr) has an atomic number of 24, which means it has 24 electrons. According to the Aufbau principle, its electronic configuration should be [Ar] 4s^2 3d^4, where [Ar] represents the configuration of argon (Ar). However, this configuration is not very stable because...
Electron impact excitation of the lowest-lying metastable states of neon, argon, krypton and xenon have been studied as a function of incident electron energy over the range from threshold to the 2P1/2 ionisation potential and at an ener... SJ Buckman,P Hammond,GC King,... - 《Journal of...
摘要: We have measured the direct cross section for electron impact excitation out of the metastable 3p4s[3/2]level (1sin Paschen's notation) into the 3p4p[5/2]level (2p) of argon from threshold to 800 eV. The direct cross section is 40 x 10cmat 10 eV. (author)...

Electron localizability indicators based on the same-spin electron pair density and the opposite-spin electron pair density are studied for correlated wavefunctions of the argon atom. Different basis sets and reference spaces are used for the multireference configuration interaction method following the ...
A method is developed for representing, in terms of a small number of integrals, the mutual potential of two ions or atoms having a rare gas electron configuration. The accuracy is the usual first approximation of the Heitler‐London method. The integrals are evaluated for two like atoms, and...
Using time-of-flight multiple electron and ion coincidence techniques in combination with a helium gas discharge lamp and synchrotron radiation, the double ionisation spectrum of disulfur (S2) and the subsequent fragmentation dynamics of its dication are investigated. The S2 sample was produced by he...
Halide perovskites show great optoelectronic performance, but their favorable properties are paired with unusually strong anharmonicity. It was proposed that this combination derives from the ns2 electron configuration of octahedral cations and associate
Energy, fine-structure, and hyperfine-structure studies of the core-excited states 1s2s2p2(5P) and 1s2p3(5S) for Be-like systems. Variational calculations using multiconfiguration interaction wave functions are carried out on the 1s2s2${\\mathit{p}}^{2}$${(}^{5}$P) and the 1s2${...
A total of 1 mg CWE was dissolved in 400 μl of DMSO containing 0.3 mg l−1 sulfur dioxide (SO2) and 10 μl diethylamine, flushed with argon and stirred overnight at room temperature. The samples were then mixed with freshly ground NaOH (200 mg), flushed with argon ...
