✦ Synopsis

The hypernerted chsin approximation is used fo calculate t&e den&y and charge profiles ar.d rhe potential difference of a fluid of &aged hard spheres nex a charred planar wdl. The charge profile is not monotonic. Recently, we [I 21 have shown that the hypernetted chain (HNC) approximation integral equations for the density profiie. p(x) = p~Iz,_(x) f I], and the charge profile, s(x) = -z~&~(x), of a model ionic fluid (consisting of charged hard spheres of charge 4ze and diameter u in a medium of dielectric constant E) near a charged hard wall located at x =--a/2, are * Work supported in part by the University of Puerto Rico Center of Ener=T nnd Ewironmentai Research (CEER) and NSF Gnnt CHE 77-0459.
