摘要

We observe a shape resonance in the scattering of two ultracold [Formula Presented] atoms, causing the colliding atoms to form a long-living compound system inside an l=2 centrifugal barrier. Its existence follows from a photoassociation experiment in a gas sample of doubly polarized [Formula Presented] atoms. Using it we are able to carry out direct determinations of the triplet scattering length for [Formula Presented], relevant to Bose-Einstein condensation experiments, and of the Rb+Rb [Formula Presented] dispersion coefficient. Consequences for the [Formula Presented] scattering length are discussed.
