Pulse-time-of-flight sound propagation (group velocity) studies of the squashing mode of superfluid He3-B in a magnetic field have revealed four of the five expected Zeeman sublevels for this J=2- mode. Variation of the pressure at very low temperatures TTc0.35 was used to sweep through the squashing mode at constant frequency (137.6 MHz). Observation of very low group velocities (down to 6 m/s) and pulse-shape analysis enabled the identification of the Jz=+2, +1, 0, and -1 sublevels. The Land g factor was found to be 0.042 near T=0 and P=19 bars as determined from the linear dependence of the Jz=+2 Zeeman component. 1988 The American Physical Society.
