abstract

• The pair correlation function [Formula presented] between like-charged colloidal particles in quasi-two-dimensional geometries is measured by optical microscopy for a wide range of particle concentrations and various degrees of confinement. The effective pair potential [Formula presented] is obtained by deconvoluting [Formula presented] via Monte Carlo computer simulations. Our results confirm the existence of a long-range attractive component of [Formula presented] and the appearance of an extra attractive term under stringent confinement. © 2003 The American Physical Society.
