摘要：

We report the observation of two kinds of novel nonhydrodynamic spin-transport phenomena of quasiparticles in superfluid B3. We find a drastic low-temperature depression of the transverse quasiparticle spin-diffusion coefficient. In addition, we have done the first measurements of the Leggett-Takagi spin-relaxation time far outside the hydrodynamic regime. The observations of spin diffusion are shown to be in quantitative agreement with a kinetic-equation approach to quasiparticle spin dynamics. © 1990 The American Physical Society.
