CHARGE OSCILLATIONS IN DEBYE-HUCKEL THEORY

The recent generalized Debye-Huckel (GDH) theory is applied to the cal culation of the charge-charge correlation function, G(zz)(r). The resu lting expression satisfies both i) the charge neutrality condition and ii) the Stillinger-Lovett second-moment condition for all T and pry, the overall ion density, and iii) exhibits charge oscillations for den sities above a ''Kirkwood line'' in the (rho(N),T)-plane. This correct s the normally assumed DH charge correlations, and, when combined with the GDH analysis of the density correlations, leaves the GDH theory a s the only complete description of ionic correlation functions, as jud ged by i)-iii), iv) exact low-density (rho(N),T) variation, and v) rea sonable behavior near criticality.
