We report experiments on deflecting cold 87Rb atoms by repulsive near-field light induced in a 200-nm-wide slit. The spatial profile is measured with a two-step photoionization scan. The number of outputted atoms from the slit increases by the amount of 40 ± 7.2% at a 5.1 ± 2.0° angle for the blue detuning of +1 GHz. We discuss the spatial profile involving an image of the atomic cloud by means of the scattering cross section.
