Relativistic variational methods and the Virial Theorem
Charlotte Froese Fischer, Michel Godefroid
In the case of the one-electron Dirac equation with a point nucleus the Virial Theorem (VT) states that the ratio of the kinetic energy to potential energy is exactly , a ratio…
Weak Correlation and Strong Relativistic Effects on the Hyperfine Interaction in Fluorine
Fatima Zahra Boualili, Messaoud Nemouchi, Michel Godefroid +1
In previous work devoted to {\it ab initio} calculations of hyperfine structure constants in nitrogen and fluorine atoms, we observed sizeable relativistic effects, a priori unexpe…
Benchmarking calculations with spectroscopic accuracy of level energies and wavelengths in W LVII - W LXII tungsten ions
Chun Yu Zhang, Kai Wang, Ran Si +5
Atomic properties of states of the W W ions are systematically investigated through two state-of-the-art methods, namely, the second-order many-body pertu…
Ab initio MCDHF calculations of the In and Tl electron affinities and their isotope shifts
Ran Si, Sacha Schiffmann, Kai Wang +2
We report multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations on the Thallium (Tl) electron affinity, as well as on the excited energy lev…
