Abstract

The single-ended, cw impedance technique has been employed to study the squashing mode of superfluid B3 in a sound cell with a path length of 381 m with ultrasound frequencies of 115.8 and 141.6 MHz. A doublet splitting of the squashing mode has been observed and the width of the splitting is dependent on the thermal gradient within the acoustic cell, which strongly suggests that the observed phenomena are induced by superflow.
