Scattering phase shifts of a meson-meson system in staggered 3-dimensional lattice QED are computed. The main task of the simulation is to obtain a discrete set of two-body energy levels. These are extracted from a 4-point time correlation matrix and then used to obtain scattering phase shifts. The results for thè = 0 and`= 2 partial waves are consistent with short-range repulsion and intermediate-range attraction of the residual meson-meson interaction.
