We have propagated transverse sound in a magnetic field in the basal plane of UPt/sub 3/, with the polarization vector oriented both in the basal-plane and perpendicular to it. We observe a strong anisotropy in the magnetic field dependence of the attenuation for the two polarizations. In a simple phenomenological model we can understand the low temperature field dependence as a natural consequence of the anisotropy with temperature in zero-field reported by us earlier. However, for increasing T, there are significant deviations from this model which are probably related to the non-standard behavior of the upper critical field in the basal plane of UPt/sub 3/. 18 refs., 3 figs.
