Ultracold molecules are formed via photoassociation in a polarized sample of cold cesium atoms. The rate of molecule formation is controlled by tuning a magnetic field. The radial dependence of the colliding wave function is probed by the photoassociation spectroscopy technique. We have in this way observed the drastic influence of the magnetic field in a broad Feshbach resonance for f=3, m=3 colliding atoms and for magnetic fields up to 30.
