Description

The drag force on an ion in low-temperature 3He is studied with a generalization of the Josephson-Lekner formalism, keeping higher-order terms in the velocity and coherence factors in the superfluid phase. In the normal state, a diffusive model for inelastic-scattering corrections provides an estimate of the onset velocity for nonlinearity in the drag force. Analytic calculations in 3He-B for elastic scattering at low and high velocity (v<Δ/psub(F) and v>Δ/psub(F)) agree qualitatively with the experimental observations near Tsub(c). (author)
