Two-pion interferometry measurements in d+Au and Au+Au collisions at √sNN=200 GeV are used to extract and compare the Gaussian source radii R\rm out, R\rm side, and R\rm long, which characterize the space-time extent of the emission sources. The comparisons, which are performed as a function of collision centrality and the mean transverse momentum for pion pairs, indicate strikingly similar patterns for the d+Au and Au+Au systems. They also indicate a linear dependence of R\rm side on the initial transverse geometric size R, as well as a smaller freeze-out size for the d+Au system. These patterns point to the important role of final-state rescattering effects in the reaction dynamics of d+Au collisions.
