Mass and spin diffusion near the λ line in dilute³He-⁴He mixtures

Research output: Contribution to journal › Article › peer-review

Abstract

We examine the possibility of using NMR and other measurements on very weak solutions of³He in liquid⁴He to investigate the superfluid phase transition. It is found that even for these very weak solutions the mass (D_m) and spin (D_s) diffusion coefficients associated with the³He behave in radically different ways:D_m is predicted to diverge as T approaches T_λ from above as (T-T_λ)^-1/3, while the behavior of D_s depends on the type of experiment, and for the ordinary spin-echo type has no particular singularity.
