A nuclear electric quadrupole moment describes the effective shape of the ellipsoid of nuclear charge distribution. The quadrupole moment depends upon the size and charge of the nucleus.

For high energy neutrino beams the requirements of large solid angle acceptance and wide bandpass can be achieved with a focusing channel composed of quadrupole cells where each cell is sequentially scaled in aperture, length and field gradient. A formalism for the design of these quadrupole focused neutrino beams with wide bandpass has been developed. The theory will be presented and the results of calculations will be given for some quadrupole focused neutrino beams. Compared to more exotic focusing techniques quadrupoles offer inherent reliability and easy maintenance. The system, which can be used in either long or short spill operation, can also be used as the front end of a muon beam for a facility that would be shared between neutrino and muon experiments. The quadrupole focusing channel does not, however, distinguish between parent particle charge and, therefore, cannot produce a pure neutrino or antineutrino beam.
In NMR, nuclei with spin ≥ 1/2 have a magnetic dipole moment so that their energies are split by a magnetic field, allowing resonance absorption of energy related to the difference between the ground state energy and the excited state. In NQR, on the other hand, nuclei with spin ≥ 1 , such as 14N, 35Cl and 63Cu, also have an electric quadrupole moment so that their energies are split by an electric field gradient, created by the electronic bonds in the local environment. Since unlike NMR, NQR is done in an environment without a static (or DC) magnetic field, it is sometimes called "zero field NMR". Many NQR transition frequencies depend strongly upon temperature. Any nucleus with more than one unpaired nuclear particle (protons or neutrons) will have a charge distribution which results in an electric quadrupole moment. Allowed nuclear energy levels are shifted unequally due to the interaction of the nuclear charge with an electric field gradient supplied by the non-uniform distribution electron density (e.g. from bonding electrons) and/or surrounding ions. The NQR effect results when transitions are induced between these nuclear levels by an externally applied radio frequency (RF) magnetic field. The technique is very sensitive to the nature and symmetry of the bonding around the nucleus. The energy level shifts are much larger than the chemical shifts measured in NMR. Due to symmetry, the shifts become averaged to zero in the liquid phase, so NQR spectra can only be measured for solids.

magnetic quadrupole is actually a group of four magnets with one pole of each adjacent magnets attract each other such that they create a Magnetic_fieldwhose magnitude Linear_functionwith the Radiusdistance from its longitudinal Coordinate_axis. This is used in Particle_beamfocusing.

An antiferroquadrupole is another name for an antiferromagnetic quadrupole - in which a magnet with two identical poles attracts rather than repels.

Yes - several planets have magnetic fields that do not even vaguely resemble Earth's current field.
