Abstract
A new analysis and new Molecular Dynamics (MD) simulations of the measurements of the mobility of O ions in dense supercritical Ar gas are reported. shows a marked dependence on the distance from the critical temperature A mobility defect appears as a function of the gas density and its maximum value occurs below the critical density. The locus of points of maximum mobility defect in the plane appears on the extrapolation of the coexistence curve into the single-phase region. MD simulations quantitatively reproduce the mobility defect near
