Two ultracold clouds of Rb87 atoms were accelerated by magnetic fields to collide at energies near a d-wave shape resonance. The resulting halos of scattered particles were imaged using laser absorption. By scanning across the resonance we observed a marked evolution of the scattering patterns due to the energy dependent phase shifts for the interfering s and d waves. Since only two partial wave states are involved in the collision process the scattering yield and angular distributions have a simple interpretation in terms of a theoretical model.4 pages, 4 figuresOther Condensed Mattertext
