Nuclear electric quadrupole moment of gold.
The nuclear quadrupole moment for (197)Au has been determined on the base of the state-of-art relativistic molecular calculations. The experimental shifts in the nuclear coupling constants in the series of molecules AuF, XeAuF, KrAuF, ArAuF, (OC)AuF, and AuH have been combined with highly accurate determinations of the electric field gradient (EFG) at the gold nucleus, obtained by molecular rel...
متن کاملThe nuclear electric quadrupole moment of antimony from the molecular method.
Relativistic Dirac-Coulomb (DC) Hartree-Fock calculations are employed to obtain the analytic electric field gradient (EFG) on the antimony nucleus in the SbN, SbP, SbF, and SbCl molecules. The electronic correlation contribution to the EFGs is included with the DC-CCSD(T) and DC-CCSD-T approaches, also in the four-component framework, using a finite-difference method. The total EFG results, al...
متن کاملThe nuclear quadrupole moment of 115In from molecular data
The nuclear quadrupole moment of In has been determined by combining the experimental nuclear quadrupole coupling constants and electric field gradients, calculated at the four-component CCSD~T! level of theory, of four indium halides. Our recommended value for the nuclear quadrupole moment of In is 770~8! millibarn. A basis set study at the Dirac–Hartree–Fock level shows a slow convergence of ...
متن کاملEffect of nuclear quadrupole moment on parity nonconservation in atoms
Nuclei with spin I ≥ 1 have a weak quadrupole moment which leads to tensor contribution to the parity non-conserving interaction between nuclei and electrons. We calculate this contribution for Yb, Fr and Ra and found it to be small. In contrast, in many lanthanides (e.g., Nd, Gd, Dy, Ho, Er, Pr, Sm) and Ra close levels of opposite parity lead to strong enhancement of the effect making it suffi...
متن کاملTable of Nuclear Magnetic Dipole and Electric Quadrupole Moments
This Table is a compilation of experimental measurements of static magnetic dipole and electric quadrupole moments of ground states and excited states of atomic nuclei throughout the periodic table. To aid identification of the states, their excitation energy, half-life, spin and parity are given, along with a brief indication of the method and any reference standard used in the particular meas...
