Transverse Spin Diffusion in 3 He- 4 He Mixtures—Part II

This is the second article in a series of two dealing with anisotropic spin diffusion. We describe a model for calculating spin-wave modes and spin-echo signals in 3He-4He mixtures. The model takes into account finite-size effects for a cylindrical sample. Using this model, we analyze the data presented in the first article, and conclude that the spin-rotation parameter saturates at low temperature in spin-polarized 6.2% 3He-4He mixture.
