Abstract

Impurity scattering of pure superfluid He by a 98% porosity aerogel near the bulk polycritical pressure was analyzed using transverse acoustic impedance experiments. In zero applied field, the equilibrium phase was found to be in the isotropic state. Superfluid phase transitions between isotropic and axial states in zero and nonzero applied fields exhibited strong supercooling.
