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