Dissipation signatures of the normal and superfluid phases in torsion pendulum experiments with 3He in aerogel

N. Zhelev, R. G. Bennett, E. N. Smith +3

We present data for energy dissipation factor (Q^{-1}) over a broad temperature range at various pressures of a torsion pendulum setup used to study 3He confined in a 98% open sili…
