Abstract
We have made measurements of the damping and resonant frequency of a vibrating wire in superfluid 3He‐B at temperatures down to about 0.12Tc at 0.0 bar and at 7.3 bar pressure. At the lowest temperatures the wire is effectively in a quasiparticle vacuum, the contribution to the damping from the quasiparticles having disappeared. In this regime the behaviour of the wire becomes strongly non‐linear reflecting the mechanical response of the superfluid condensate.Keywords
