nuclear spin

an intrinsic form of angular momentum possessed by atomic nuclei containing an odd number of nucleons (protons or neutrons).

nuclear spin

An MRI term referring to an intrinsic property of nuclei with an odd numbers of protons and/or neutrons to exhibit angular momentum and a magnetic moment; even-numbered nuclei do not produce NMR signals.

Many of us could name a handful of Spanish varieties quite easily, like Tempranillo, Garnacha, Monastrell, but cross the border and other than Touriga Nacional most of us would be making the nuclear spin tomograph light up like a Christmas tree.
Instead, as originally intended, (3) he enthusiastically pursued an untrodden realm, optical spectroscopy for nuclear structure study that resulted in valuable observations (1) by which Pauli was inspired to assume nuclear spin.
When the sample was held at this cryogenic temperature, the nuclear spins of about 37 percent of the ions - a typical benchmark to measure quantum coherence - remained in their superposition state for three hours.
The nuclear spins of the 10 billion or so phosphorus ions used in this experiment were all placed in the same quantum state.
Using this characteristics, the joint research group has produced and detected entanglement between two quantum bits by treating the nuclear spin of a phosphorus atom as one quantum bit and the captured electron's spin as another quantum bit.
Perturbed magnetization and its recovery (relaxation) to the equilibrium state can be detected and information on the nuclear spin environment of the sample or tissue can be obtained.

An atom's spin, like its charge, is an intrinsic property of atomic nuclei, and the PICO bubble chamber exploits that fact by using a fluid component - fluoride - with a relatively large nuclear spin.
An atomic nucleus consists of both protons and neutrons, and the advantage of using the nuclear spin as a qubit is that the nucleus is well protected, and nearly impervious to unwanted electromagnetic disturbance, which is a condition for keeping the sensitive information in the qubit intact.
