24 May 2004 | Journal: | Physical Review Letters 93, 173201 (2004) DOI: 10.1103/PhysRevLett.93.173201 | Subject: | Other | cond-mat.other | Abstract: | We report on the direct imaging of s and d partial-wave interference in cold collisions of atoms. 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. | Source: | arXiv, cond-mat/0405544 | Other source: | [GID 292409] pmid15525073 | Services: | Forum | Review | PDF | Favorites |
