Abstract
We present new experimental and theoretical studies of magnetic relaxation in 3HeB. Methods are developed for the measurement of relaxation using either CW or Pulsed NMR. Both methods make use of the properties of the Homogeneously Precessing Domain. Terms corresponding to intrinsic (Leggett-Takagi), spin diffusion and surface relaxation are distinguished. Theoretical results for the spin diffusion coefficient and the Leggett-Takagi relaxation time, which display nonhydrodynamic anomalies, are compared with experiment.
