Abstract

Nearly all of the previous work on the diffusion of 3He in superfluid 3He-4He solutions has been done on solutions whose molar 3He concentration χ was 5% or less. Husa et al.1 reported measurements for χ = 12% for T < 1.2°K, and Horvitz and Rorschach2 reported some indirect estimates for χ = 14%. This paper reports measurements of the diffusion coefficient by the spin-echo method for solutions with χ = 5%, 9%, 14%, and 24% for 0.9 < T < 2.5°K.†
