Abstract
Attenuation measurements of longitudinal ultrasound in superconducting UPt/sub 3/ show a peak, below H/sub c2/, that depends strongly on the orientation of the field relative to the c-axis. This peak is seen only with longitudinal and not with transverse sound. It is show that, as the field is tipped away from the c axis into the basal plane. H/sub FL/ decreases from 1.3 T to 0.58 T (at the lowest temperature). The temperature dependence of H/sub FL/ for all orientations of the field is the same-a flat region, followed by a slow decrease in H/sub FL/ with increasing temperature.<>
