Abstract

Measurements have been made of the normal fluid fraction of superfluid3He-B at eight different pressures between 0 and 29.2 bar. The minimum temperatures were such that ρ n /ρ was reduced to less than 0.5%. The experiments, carried out independently at Cornell and Texas A&M Universities, used similar Andronikashvilli-type torsional oscillators. The results are qualitatively similar, but show significant differences due to the use of different temperature standards. Both sets of results are presented in tabular form. The inconsistencies in the temperature scales preclude the examination of the results for possible strong coupling effects.
