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...

The interacting boson model is extended to describe the spectroscopy of superdeformed bands. Microscopic structure of the model in the second minimum is discussed and superdeformed bosons are introduced as the new building blocks. Solutions of a quadrupole Hamiltonian are implemented through the 1/N expansion method. Effects of the quadrupole parameters on dynamic moment of inertia and electric...

Nuclear forces violating parity and time reversal invariance (P,T -odd) produce P,T -odd nuclear moments, for example, the nuclear Schiff moment. In turn, this moment can induce the electric dipole moment in the atom. The nuclear Schiff moment is predicted to be enhanced in nuclei with static quadrupole and octupole deformation. The analogous suggestion of the enhanced contribution to the Schif...

We studied the electric quadrupole interactions of Oxygen isotopes in a T i 0 2 single crystal. For l 3 0 and 1 9 0 nuclei, quadrupole coupling constants were measured by the /3-NMR technique, and for the 1 7 0 nucleus the FT-NMR technique was utilized. We synthesized a T i0 2 single crystal which was enriched in 1 7 0 up to 5 atom % to observe NMR signals without any perturbations from impurit...

Nonequilibrium molecular dynamics calculations of the shear viscosity of supercritical carbon dioxide along the 313 K isotherm are reported. Three different intermolecular potential models of increasing complexity are considered: a spherically symmetric Lennard-Jones potential, a two-site Lennard-Jones potential, and a three-site potential which includes a quadrupole-quadrupole moment. Results ...

In this letter we dynamically determine the quadrupole mass moment Q of the magnetic white dwarf WD 0137-349 by analyzing the period of the recently discovered brown dwarf moving around it in a close 2-hr orbit. It turns out that a purely Newtonian model for the orbit of WD 0137-349B, assumed circular and equatorial, is adequate, given the present-day accuracy in knowing the orbital parameters ...

We present results for electronic momentum distribution n(k) of deformed sodium clusters in the framework of the Kohn-Sham formalism. We discuss properties of both spheroidal clusters and fission configurations. For spheroidal clusters we have analyzed properties of total and single-particle electronic momentum distribution. The results show that deformation has more of an effect on the latter,...

Hole burning, which is attributed to optical pumping of nuclear-quadrupole levels, has been observed in the stoichiometric rare-earth compound, EuP5O14 . The long lifetime of these holes (-60 min) implies slow nuclear-spin flip-flop rates. The small magnetic moment of Eu3+ has prevented conventional magnetic-resonance measurements on Eu3+ compounds, but hole burning provides a sensitive method ...
