Differential scattering measurements from a collider for ultracold atoms

We present a method for measuring differential cross sections from scattering halos produced by cold collisions between ultracold atomic clouds. Our scheme incorporates the dynamics of scattered particles within a harmonic potential that is used as a collider for the clouds. We demonstrate how to transform an experimentally acquired absorption image in order to obtain the angular scattering probability density.
