Nuclear magnetic quadrupole moments in the single-particle approximation.
نویسندگان
چکیده
Static magnetic quadrupole moment of a nucleus, induced by T-and P-odd nucleon-nucleon interaction, is investigated in the single-particle approximation. Models are considered allowing for analytical solution. The problem is also treated numerically in a Woods-Saxon potential with spin-orbit interaction. The stability of results is discussed.

Approximate particle number projection with density dependent forces: Superdeformed bands in the A=150 and A=190 regions
We derive the equations for approximate particle number projection based on mean field wave functions with finite range density dependent forces. As an application ground bands of even-A superdeformed nuclei in the A = 150 and A = 190 regions are calculated with the Gogny force. We discuss nuclear properties such as quadrupole moments, moments of inertia and quasiparticle spectra, among others,...

Collinear laser spectroscopy experiments in the LuI transition 5d6s D3=2 ! 5d6s6p D3=2 were performed on all lutetium isotopes in the range of 161 Lu. The nuclear spins, magnetic moments and quadrupole moments were determined from the hyperfine structures observed for 19 ground states and 11 isomers. Variations in the mean square charge radii as a function of neutron number were obtained from t...
متن کاملQuadrupole moments of sd-shell nuclei.
Shell-model calculations are presented for electric quadrupole moments of A =17—39 nuclei. The shell-model wave functions, which span the complete Ods/2-1sl/2 Dd3/2 model space in all instances, are obtained by diagonalizing an sd-shell Hamiltonian which consists of a fixed singleparticle energy spectrum and a single set of two-body matrix elements scaled as a function of the mass number A. Res...
متن کاملQuasiantiferromagnetic 120° Neel state in two-dimensional clusters of dipole-quadrupole-interacting particles on a hexagonal lattice
The magnetostatic interactions of colloidal particles, "capped" with radially magnetized ColPt multilayers, are modeled. Motivated by experiment the particles are arranged in microscopic two-dimensional clusters on a hexagonal lattice and are free to rotate. The thermodynamically stable states of clusters containing up to 108 particles are calculated theoretically by means of Monte Carlo simula...
متن کاملNuclear Schiff moment in nuclei with soft octupole and quadrupole vibrations
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...
