A high-resolution acoustic impedance technique has been used to investigate the real squashing, J = 2, mode in /sup 3/He-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 J/sub z/ = 0 mode. This new splitting is observed to be T/T/sub c/, pressure and/or frequency dependent, but is independent of magnetic field. In Happrox. =0, additional features have been observed which can be associated with dispersion-induced mode splittings.
