Abstract

Zero-sound measurements have been performed in ³He-B for P < 5 bar. An attenuation peak near T_c has been completely resolved for P < 2 bar and is greater than the theoretical predictions for the pair-breaking contribution. In addition, while c_φ remains constant until hv ∼ 2δ (T), v_g is observed to decrease by ≈ 35%.

worthy of additional investigations. We acknowledge contributions from Jin Duo in the early design and assembly of the experiment. We thank Pat R. Roach and Argonne National Laboratory who made equipment available to us. We are grateful to Daniels et al. for kindly communicating their work to us prior to publication and have benefited from conversations with J. Saunders and J.R. Owers-Bradley. The measurements were performed in the Low Temperature Facility of the Northwestern University Materials Research Center supported in part by the NSF-MRL program Grant No. 79-23573.
