The target condensate scatters the incident atom laser pulse. From the spatial distribution of scattered atoms, one can infer important properties of the target condensate and its interaction with the probe pulse. As an example, we measure the s-wave scattering length that, in low energy collisions, describes the interaction between the |F = 1,mF = −1> and |F = 2,mF = 0> hyperfine ground states in 87Rb.8 pages"OSA will grant the authors permission to deposit the publisher’s pdf from their Optics Express articles into the repository with the proper citation (reference number or journal /volume/page/year citation)." - from email received from Authorized Agent, The Optical Society, 27/05/10atom opticsBose-Einstein condensateseffects of collisions2008-08-2210.1364/OE.16.0138932015-12-08
