Abstract

We report a method for determining the rate of diffusion of exchange energy in solid

{He}^{3}

. Over the temperature range 0.05-0.12°K, we obtain a temperature-independent diffusion constant

D_{E} = (0.75 \pm 0.15) J a^{2}

, where

a

is the nearest-neighbor distance and

J

the exchange integral.
