Abstract

Spin polarized helium 3 (3He↑) and also atomic hydrogen (H↓) are systems exhibiting a number of unusual and Interesting properties at low temperature.1 This is true even for dilute polarized gases in spite of the weakness of the nuclear magnetic interaction between atoms. The changes in the macroscopic properties of the gas with the nuclear polarization P are pure consequences of the indistinguishability of the particles and of the symmetrization principle in quantum mechanics. The transport properties of the gas, such as viscosity and thermal conductivity, have been calculated and found to be strongly dependent on P below a few kelvins.1
