Abstract

New vapor-pressure measurements of

{He}^{3}

{He}^{4}

solutions in the region between 0.5 and 1.2°K have been made and are used to calculate changes in the chemical potential. Special emphasis is directed towards the region of the tricritical point. The variation of the chemical potential and its derivative along certain paths leading to the critical point yields critical indices which satisfy the scaling relation proposed by Griffiths.
