This chapter starts the review of the transport properties of ions and electrons in liquid 3He. In contrast with its 4He bosonic companion, the lighter helium isotope is made of fermions. It is a physical example of a Fermi liquid. It is thus expected that ions couple to the liquid in a peculiar way that can be investigated by studying how they drift under the action of an electric field. The ion transport in normal liquid 3He at high temperatures (T>1 K), well above its superfluid transitions, is discussed.Less

This chapter presents the experimental results of the study of the mobility of ions in liquid 3He at the liquid-vapor transition. It shows how electrostriction in a region in which the compressibility is the highest affects both positive ions and negative ions, though in a quantitatively different way that depends on the different structure of the two kinds of charges. The interesting observation that the mobility minima are located on the extrapolation of the coexistence curve into the one-phase region is emphasized. The correlation of this behavior with that of O2 - ions in dense argon gas is put into evidence.Less
