Title: Splitting of the squashing collective mode of superfluid /sup 3/He-B by a magnetic field

Abstract

Pulse--time-of-flight sound propagation (group velocity) studies of the squashing mode of superfluid /sup 3/He-B in a magnetic field have revealed four of the five expected Zeeman sublevels for this J = 2/sup -/ mode. Variation of the pressure at very low temperatures (T/T/sub c/less than or equal to0.35) was used to sweep through the squashing mode at constant frequency (137.6 MHz). Observation of very low group velocities (down to approx.6 m/s) and pulse-shape analysis enabled the identification of the J/sub z/ = +2, +1, 0, and -1 sublevels. The Lande g factor was found to be 0.042 near T = 0 and P = 19 bars as determined from the linear dependence of the J/sub z/ = +2 Zeeman component.
