As of November 2000, nuclear spin temperatures below 100 pK were reported for an experiment at the Helsinki University of Technology Low Temperature Lab.

His devices consist of rapidly spinning disks of brass, a material made up largely of elements with a total half-integer nuclear spin.
43.
Nuclear spin is useful to perform single-qubit operations, but to make a quantum computer, two-qubit operations are also required.
44.
The manipulation of " nuclear spin " by radiofrequency waves ( nuclear magnetic resonance ) is important in chemical spectroscopy and medical imaging.
45.
It is based on the effect where nuclear spin cross-relaxation after excitation by a radio pulse depends on the distance between the nuclei.
46.
His techniques for using nuclear magnetic resonance to discern the magnetic moment and nuclear spin of atoms earned him a Nobel Prize for Physics in 1944.
47.
Their idea was to employ a weak magnetic field instead of a strong one, with which they hoped to detect the nuclear spin of sodium.
48.
As is true for ortho and para hydrogen the nuclear spin function of the two hydrogens has three symmetric ortho states and one antisymmetric para states.
49.
Some atomic nuclei possess a magnetic moment ( nuclear spin ), which gives rise to different energy levels and resonance frequencies in a magnetic field.
50.
Nuclear selection rules require L-values greater than two to be accompanied by changes in both nuclear spin ( ) and parity ( ? ).
