    "abstract": "We report the direct observation of a novel type of rainbow caustic. In\ncontrast to known examples, this caustic originates from a dissipative,\nstochastic process. We have observed this using cold ^{87}Rb atoms bouncing\ninelastically on an evanescent-wave atom mirror. The caustic appears as a sharp\npeak at the lower edge of the asymmetric velocity distribution of the bouncing\natoms. The stochastic process is a spontaneous Raman transition due to photon\nscattering during the bounce. The results are in good agreement with a\nclassical calculation.",
