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…
Theoretical Hyperfine Structures of F~I and O~I
Nouria Aourir, Messaoud Nemouchi, Michel Godefroid +1
Multiconfiguration Hartree-Fock (MCHF) and multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations are performed for the , , $2p^4(^{3}P)3…
Relativistic effects on the hyperfine structures of 2p4(3P)3p 2Do, 4Do and 4Po in 19F I
Thomas Carette, Messaoud Nemouchi, Jiguang Li +1
The hyperfine interaction constants of the 2p4(3P)3p 2Do_{3/2,5/2}, 4Do_{1/2-7/2} and 4Po_{1/2-5/2} levels in neutral fluorine are investigated theoretically. Large-scale calculati…
Saturation spectra of low lying states of Nitrogen: reconciling experiment with theory
Thomas Carette, Messaoud Nemouchi, Per Jönsson +1
The hyperfine constants of the levels 2p2(3P)3s 4P_J, 2p2(3P)3p 4Po_J and 2p2(3P)3p 4Do_J, deduced by Jennerich et al. [Eur. Phys. J. D 40 (2006) 81] from the observed hyperfine st…
Ab initio calculations of 14N and 15N hyperfine structures
P Jönsson, T Carette, M Nemouchi +1
Hyperfine structure parameters are calculated for the 2p2(3P)3s 4P_J, 2p2(3P)3p 4Po_J and 2p2(3P)3p 4Do_J levels, using the ab initio multiconfiguration Hartree-Fock method. The th…
Irreducible tensor-form of the relativistic corrections to the M1 transition operator
M. Nemouchi, M. R. Godefroid
The relativistic corrections to the magnetic dipole moment operator in the Pauli approximation were derived originally by Drake (Phys. Rev. A 3(1971)908). In the present paper, we…
