This gives the star a quadrupole moment that changes with time, and it will emit gravitational waves until the deformities are smoothed out.
22.
Hans Bethe identified the discovery of the deuteron's quadrupole moment as one of the important events during the formative years of nuclear physics.
23.
The quadrupole moment tensor has thus 9 components, but because of the symmetry and zero-trace property, only 5 of these are independent.
24.
Such a configuration cancels the dipole moment and gives a quadrupole moment, and its field will decrease at large distances faster than that of a dipole.
25.
Comparing the quadrupole moment of different arenes is a useful qualitative tool to predict trends in cation-? binding, since it roughly correlates with interaction strength.
26.
In order to use electrostatics to predict energies, the full electrostatic potential surface must be considered, rather than just the quadrupole moment as a point charge.
27.
For example, the largest angular-scale measurement, the quadrupole moment, is somewhat smaller than the Model would predict, but this discrepancy is not highly significant.
28.
In atoms, hyperfine structure occurs due to the energy of the nuclear electric quadrupole moment in the electric field gradient due to the distribution of charge within the atom.
29.
Another relaxation mechanism is the electrostatic interaction between a nucleus with an electric quadrupole moment and the electric field gradient that exists at the nuclear site due to surrounding charges.
30.
Perl's thesis described measurements of the nuclear quadrupole moment of sodium, using the atomic beam resonance method that Rabi had won the Nobel Prize in Physics for in 1944.
