Abstract
Particle interactions were directly determined from the lateral compression of two-dimensional plasma dust crystals confined in a parabolic potential well. Measured particle separations combined with an equation of state for the crystal were used to derive values for the particle screening length an d the charge on the particles. The shape of the parabolic potential well wa s confirmed by observing trajectories of single particles falling within th e well. No evidence of a lateral particle-particle binding was observed.
