Abstract

Measurement of the surface tension of superfluid helium in the neighborhood of the λ-transition are presented. The data are analyzed to obtain the behavior of the "singular" part of the surface tension, which is discussed in the light of the calculation by Sobyanin, based on the Ginzburg-Pitaevskii phenomenological theory, and the results from scaling theory as obtained by Hohenberg. It is found that the behavior of the surface tension suggests a divergent and negative specific heat above and below T_λ and that the free surface correlation length is given by ξ=(1.5±0.4)Å|ε|^-2/3, in good agreement with the coherence length in the Mamaladze version of the phenomenological theory.
