Transport properties in a spin polarized gas (II)
Résumé
The general results obtained in a preceding article (with the same title) are appliede to the study of transport phenomena in a spin polarized gas at low temperature, with particular emphasis on particle indistinguishability effects in collisions. A simple theory of spin diffusion is pressented and the response of the gas to a spin orientation gradient is calculated, taking into account the "identical spin rotation effect". The hydrodynamic equations of evolution of the spin orientation give rise to oscillations (spin waves). .....
