Scattering patterns

Below we show absorption images acquired at a fixed time after collision (a quarter of a radial trap period), but at different collision energies. It is obvious that there is a dramatic change in the patterns particles are scattered in. This is the result of quantum interference between exactly two so-called partial waves (an s-wave and a d-wave).

Click here to see a movie of the cold collision of two ultracold atomic Rubidium clouds at an energy where there is major d-wave contribution to the scattering pattern.
