We have observed a series of oscillations in the transverse acoustic response of superfluid B3, which, in analogy with earlier observations involving longitudinal sound, suggest an evolving standing-wave pattern. These oscillations were observed with 60.8 MHz transverse sound at pressures between 1 and 3 bars. The change in the reciprocal of the phase velocity can be obtained from this data, and it is compared with a recent theoretical prediction [G. F. Moores, and J. A. Sauls, J. Low Temp. Phys. 91, 13 (1993)].
