    "abstract": "We report on experiments on an evanescent-wave mirror for cold $^{87}$Rb\natoms. Measurements of the bouncing fraction show the importance of the Van der\nWaals attraction to the surface. We have directly observed radiation pressure\nparallel to the surface, exerted on the atoms by the evanescent-wave mirror. We\nanalyze the radiation pressure by imaging the motion of the atom cloud after\nthe bounce. The number of photon recoils ranges from 2 to 31. This is\nindependent of laser power, inversely proportional to the detuning and\nproportional to the evanescent-wave decay length. By operating the mirror on an\nopen transition, we have also observed atoms that bounce inelastically due to a\nspontaneous Raman transition. The observed distributions consist of a dense\npeak at the minimum velocity and a long tail of faster atoms, showing that the\ntransition is a stochastic process with a strong preference to occur near the\nturning point of the bounce.",
