ION MOBILITY AT THE LIQUID-VAPOR TRANSITION IN 3HE
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.
Keywords: liquid 3He, normal liquid, liquid-vapor transition, hydrodynamic mobility, hydrodynamic radius, compressibility, O2- ions, electrostriction, argon gas
