Abstract

Recent measurements of the osmotic pressure of mixtures of He3 in superfluid He4 demonstrate the feasibility of temperature measurement using either of two experimental techniques. The first method, developed by H. London, measures the osmotic pressure of the saturated mixture and is useful for thermometry down to 30 mK. The second method, discussed in this paper, uses very dilute mixtures and is useful down to 10 mK.
