Investigation of intravalence, core–valence and core–core electron correlation effects in polonium atomic structure calculations
نویسنده
چکیده
A detailed investigation of the atomic structure and radiative parameters involving the lowest states within the 6p, 6p6d, 6p7s, 6p7p and 6p7d configurations of neutral polonium is reported in the present paper. Using different physical models based on the pseudo-relativistic Hartree–Fock approach, the influence of intravalence, core–valence and core–core electron correlation on the atomic parameters is discussed in detail. This work allowed us to fix the spectroscopic designation of some experimental level energy values and to provide for the first time a set of reliable oscillator strengths corresponding to 31 Po I spectral lines in the wavelength region from 175 to 987 nm. & 2014 Elsevier Ltd.

Relativistic Pseudopotentional Incorporating Core/Valence Polarization and Nonlocal Effects
A relativistic pseudopotentional (RPP) for use in ab initio molecular electronic structure calculations is derived in the context of the relativistic effective core potential (REP) method of Lee et al. The resulting atom-specific RPP has salient features of the REP imbedded within it while retaining the form of a functional that is dynamically defined at runtime when used in calculations on mol...

Relativistic Pseudopotentionals (RPPs) are a new form of relativistic effective core potentials (RECP) that are based on extending the usual two-space representation of atomic electrons (core and valence) to three spaces: core, outer core, and valence. The RPP has embedded within it the so-called small-core RECP, viz., one that relegates the outer core electrons to the valence space. The RPP is...
متن کاملAccurate correlation consistent basis sets for molecular core–valence correlation effects: The second row atoms Al–Ar, and the first row atoms B–Ne revisited
Correlation consistent basis sets for accurately describing core–core and core–valence correlation effects in atoms and molecules have been developed for the second row atoms Al–Ar. Two different optimization strategies were investigated, which led to two families of core–valence basis sets when the optimized functions were added to the standard correlation consistent basis sets (cc-pVnZ). In t...

The relativistic pseudopotential (RPP) calculations of valence (spectroscopic, chemical etc.) properties of molecules are very efficient because the modern two-component RPP methods allows one to treat very accurately the correlation and relativistic effects for the valence electrons of a molecule and to reduce dramatically the computational cost. The valence molecular spinors are usually smoot...

To calculation non-bonded interaction of the [CoCl6]3- complex embedded in nano ring, we focus on the single wall boron-nitride B18N18 nano ring. Thus, the geometry of B18N18 nano ring has been optimized by B3LYP method with EPR-II (Electron paramagnetic resonance) basis set and geometry of the [CoCl6]3- complex has been optimized at B3LYP method with Aldrich’s VTZ basis set and Stuttgart RSC 1...
