Nuclear Dipole Moments and Shielding Constants of Light Nuclei Measured in Magnetic Fields

On shielding of nuclear electric dipole moments in atoms

We demonstrate explicitly that some recent calculations of atomic electric dipole moments (EDM) are incomplete. A contribution overlooked therein is pointed out. When included, it cancels exactly the result of those calculations, and thus restores the standard conclusions for nuclear EDM in atoms. The existence of EDMs of elementary particles, nuclei, and atoms is forbidden by CP invariance. Th...

The Nuclear Magnetic Shielding of the F-Nuclei in KZnF3

Using solid state multiple pulse techniques the magnetic shielding tensors a of the F nuclei in a single crystal of KZnF 3 have been measured. The F~-site symmetry in KZnF3 , D 4 h , allows axial anisotropy of a and determines fully the principal shielding directions. Using CaF 2 as the reference compound, the average shielding is + 85 ppm and the shielding anisotropy is + 18.4 ppm. These resul...

Table 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...

Magnetic moments of light nuclei from lattice quantum chromodynamics.

We present the results of lattice QCD calculations of the magnetic moments of the lightest nuclei, the deuteron, the triton, and ^{3}He, along with those of the neutron and proton. These calculations, performed at quark masses corresponding to m_{π}∼800  MeV, reveal that the structure of these nuclei at unphysically heavy quark masses closely resembles that at the physical quark masses. In part...
