| 21. | Applying such a pulse to a set of nuclear spins simultaneously excites all the single-quantum NMR transitions.
|
| 22. | Wu's experiment compared the distribution of gamma and electron emissions with the nuclear spins in opposite orientations.
|
| 23. | These include molecules in which the quantum states of electron and nuclear spins can be controlled with exquisite precision.
|
| 24. | Nuclear spin is best known for its crucial role in the NMR / MRI technique for chemistry and biochemistry analysis.
|
| 25. | Wu's observation was that more ?-rays were emitted in the opposite direction to the nuclear spin.
|
| 26. | This type of emission ( Gamow-Teller transition ) changes nuclear spin by a unit of 1 to compensate.
|
| 27. | These fluctuations produce transitions between the nuclear spin states in a similar manner to the magnetic dipole-dipole interaction.
|
| 28. | It is this magnetic moment that allows the observation of NMR absorption spectra caused by transitions between nuclear spin levels.
|
| 29. | Observations of the energy levels of atoms and molecules were inconsistent with the nuclear spin expected from proton electron hypothesis.
|
| 30. | Yet it is possible to use the 29 Si nuclear spin of the SiV as a qubit for quantum information applications.
