Atomic calculations of the hyperfine-structure anomaly in gold
نویسندگان
چکیده
The magnetic hyperfine structure constants have been calculated for low-lying levels in neutral gold atom and gold-like ion of mercury taking into account Bohr--Weisskopf (BW) effect. BW effect is represented as a product atomic nuclear ($d_\mathrm{nuc}$) factors. We the factors, which enable one to extract BW-correction values far from stability nuclei experimental data. possible uncertainty our calculations estimated by comparison with available It has shown that standard single-particle approach $d_\mathrm{nuc}$ calculation reasonably well describes data $11/2^-$ isomers $3/2^+$ ground state $\rm ^{199}Au$. At same time, it fails describe constant $^{197}\mathrm{Au}$. This indicates more pronounced configuration mixing ^{197}Au$ than

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Relativistic calculations of atomic structure
This paper is intended to give a review on relativistic atomic structure calculations [1] with emphasis on the Multiconfigurational-Dirac-Foek method, Dr Crossley has summarized in his preeeeding paper most of the non-relativistic methods whieh lead to good binding energies and transition probabilities. Both quantities are espeeially important in astrophysies and plasma physies. Sinee relativis...
