    "abstract": "The specular reflectivity of slow, metastable neon atoms from a silicon\nsurface was found to increase markedly when the flat surface was replaced by a\ngrating structure with parallel narrow ridges. For a surface with ridges that\nhave a sufficiently narrow top, the reflectivity was found to increase more\nthan two orders of magnitude at the incident angle of 10 mRad from the surface.\nThe slope of the reflectivity vs the incident angle near zero was found to be\nnearly an order of magnitude smaller than that of a flat surface. A grating\nwith 6.5% efficiency for the first-order diffraction was fabricated by using\nthe ridged surface structure.",
