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 کاملElectric Quadrupole Moment of the 14 N Nucleus Determined by ab initio Cl Calculation on NH
Based on the calculated electric field gradient (q) from ab initio Cl wavefunctions with large basis set (including / functions on N and d functions on H) and the experimental nuclear quadrupole coupling constant (e Q q) for nitrogen in N H 3, an improved value o f the quadrupole moment o f l4N is proposed as Q ('4N ) = 2.08 x 10~ 26 cm2. The value calculated using a wavefunction near the Hartr...
متن کاملIntrinsic quadrupole moment of the nucleon
We address the question of the intrinsic quadrupole moment Q0 of the nucleon in various models. All models give a positive intrinsic quadrupole moment for the proton. This corresponds to a prolate deformation. We also calculate the intrinsic quadrupole moment of the ∆(1232). All our models lead to a negative intrinsic quadrupole moment of the ∆ corresponding to an oblate deformation. PACS numbe...
متن کاملElectric-dipole, electric-quadrupole, magnetic-dipole, and magnetic-quadrupole transitions in the neon isoelectronic sequence
Excitation energies for 2l23l8 hole-particle states of Ne-like ions are determined to second order in relativistic many-body perturbation theory ~MBPT!. Reduced matrix elements, line strengths, and transition rates are calculated for electric-dipole (E1), magnetic-quadrupole (E2), magnetic-dipole (M1), and magneticquadrupole (M2) transitions in Ne-like ions with nuclear charges ranging from Z51...
