The single-ended, cw, impedance technique has been employed to study the squashing mode of 3.5. Superfluid 3HeB in a sound cell with a path length of 381 μm with ultrasound frequencies of 115.8 MHz and 141.6 MHz. A doublet splitting of the squashing mode has been observed and the magnitude of the splitting depends on the pressure. In addition, a "bump-like" structure, preceding the pair-breaking edge by about 3.5 MHz, has been observed with a sound frequency of 64.3 MHz in an applied magnetic field at pressures ranging from 4 to 7 bar.
