they form adiffusecloud of negative charge that occupies nearly the entire volume of the atom. The arrangement of electrons in orbitals and shells around the nucleus is referred to as theelectronic configurationof the atom. This electronic configuration determines not only the size of an individual...

The ground state of At−has a 6p61S0configuration. Therefore, this state shows no term, fine or hyperfine structure splitting. Further, as for all other halogen negative ions, it is the only bound state. Hence, all At−ions in the ion beam are in the same quantum state, and the re...
Kuniyoshi EBINA, Makoto KABURAGI, in Strongly Coupled Plasma Physics, 1990 3 ADIABATIC APPROXIMATION Except probably for the situations where the electron localization couples with the ion motion, we can take the trace of electron degrees of freedom first with a fixed ion configuration giving the eff...
As the result of mixing with the doubly excited electronic configuration, the fundamental gap in the ground electronic state of PAC widens to ca. 1.8 – 2.2 eV depending on the density functional employed. In the excited singlet electronic state, the band gap closes; thus, leading to ...
Finally, using the configuration-interaction method, we find the states of excitons, and the strength of their coupling to light. We discuss the calculation in more detail in the “Methods” section, where material parameters are also given in Table 1....

On the consistent definition of spin–orbit effects calculated by relativistic effective core potentials with one-electron spin–orbit operators: Comparison of spin–orbit effects for Tl, TlH, TlH 3 , TlH 3 , PbH 2 , PbH 2 , and PbH 4 PbH 4 ...
A double-hexapole corrector system was used in the former case, whereas multiple quadrupole–octupole elements were originally used in the latter configuration. The high-coherence FEG electron source contributed significantly to the overall success of these developments because considerable image detail ...
‘low’ primary energies that can reveal the precise atomic configuration of point defects or grain boundaries. It should be noted that, although the graphene lattice is remarkably stable under a 60–80kV electron beam, many of the defect configurations, the graphene edges, or adsorbates and ...
