Quantum Properties Of Spin Polarized 3he (3he↑)
Résumé
The effect of a high polarization of the nuclear spins in an ensemble of 3He atoms are theoretically investigated. One can see from the Pauli antisymmetrization principle that a non-zero nuclear polarization results in an increase of the kinetic energy of the atoms and in a decrease of the effectiveness of their interactions. As a consequence, the macroscopic properties of gaseous, liquid or solid 3He at low temperatures may be significantly altered. Several examples of these changes are briefly discussed in this article : modifications of the transport properties of gaseous 3He at a few degree Kelvin, of the liquid-vapour and liquid-solid phase diagram, etc.
