Spin Wave Spectrum

After a brief review of experiment and theory for transverse spin waves in normal liquid 3He, we compare previously published data at 0, 6.3, and 12.3 bar (1 bar = 100 kPa) in superfluid 3He–B with a new version of the theory of Combescot for the spin-wave spectrum. The new theory includes the Fermi-liquid parameters [Formula: see text] and [Formula: see text] (as well as [Formula: see text], which was in the old version). The equations give an excellent fit to the data at 0 bar using values of [Formula: see text] and [Formula: see text] from the normal liquid, and [Formula: see text] from the B-phase susceptibility. At 6.3 bar, the fit is not quite so good, perhaps because of nontrivial strong-coupling effects. At 12.3 bar, the experimental uncertainties make the comparison inconclusive.
