By use of the resonant metastability‐exchange process, a metastable‐atom beam possessing all genuine qualities of a “ natural ” ground‐state atom nozzle beam is prepared. Owing to the angular narrowness (0.35 mrad) and smallness of the effective source diameter (15 μm) of this beam, the scattering of metastable atoms by a silicon‐nitride nano‐slit grating is investigated in detail, in a partially coherent regime. The elastic scattering exhibits high‐order diffraction peaks combined with a standard van der Waals deflection effect. When a static magnetic field is present, surface‐induced exo‐energetic transitions among Zeeman sub‐levels are observed.
