| 1. | Relaxation of the nuclear spin system is crucial for all NMR applications.
|
| 2. | I know, that nuclear and electron spin systems are the standard example.
|
| 3. | The number " " is the multiplicity of the spin system.
|
| 4. | This approach works for distinguishable particles or the spin systems.
|
| 5. | These results agree with numerous numerical studies of model quantum spin systems in two dimensions.
|
| 6. | An example of such a component is a spin system within a body, as follows.
|
| 7. | Let's take the example of nuclear spin systems.
|
| 8. | It is possible to add energy to the spin system using radio frequency ( RF ) techniques.
|
| 9. | In systems with a large number of degrees of freedom, like spin systems, Monte Carlo integration is required.
|
| 10. | This allows NDR to cool the nuclear spin system to very low temperatures, often 1 �K or below.
