Abstract

We have measured positive-ion mobilities in liquid 3He down to 3 mK. At 5 bar the low temperature mobility is given by mu = (0.17 - 4.41 lnT) x 10^-6 m^2/Vs. At 27 bar two mobilities are seen, mufast= (-12.85 - 6.21 lnT) x 10^-6 m^2/Vs and muslow = (-6.26 - 3.64 lnT) x 10^-6 m2/Vs. At temperatures near the discontinuity we see multiple mobilities and time-dependent conversion from one species of ion to another.
