Abstract
We demonstrate a gravito-optical surface trap for Cs atoms which exploits cooling in an evanescent light wave. About 1 atoms were cooled down to 3 μK and formed a sample with a mean height of above the surface of a dielectric prism. The trap does not use a magnetic field and leads to very small atomic level perturbations. The excited-state population of the stored atoms is and collisional losses are strongly suppressed.
