摘要：

We studied the diffusion of atomic hydrogen in saturated He-3 (0.3 < T < 0.4 K) and He-4 (0.6 < T < 1.1 K) vapor. Using the Carr-Purcell-Meiboom-Gill spin echo method near zero field, we were able to measure the diffusion coefficient for a wide range of temperatures and we could determine the diffusion cross section Q(D) at very low temperatures. Q(D) was observed to decrease with temperature in agreement with the calculation by Jochemsen et al.
