Abstract

A high-resolution acoustic impedance technique has been used to investigate the real squashing, J=2, mode in He3-B. For a magnetic field perpendicular to the sound propagation direction, six components have been observed. The two center states appear to be a splitting of the Jz=0 mode. This new splitting is observed to be dependent on TTc, pressure, and/or frequency, but is independent of magnetic field. In H≅0, additional features have been observed which can be associated with dispersion-induced mode splitting.
