    "abstract": "We create a gray optical lattice structure using a blue detuned laser field\ncoupling an atomic ground state of angular momentum J simultaneously to two\nexcited states with angular momenta J and J-1. The atoms are cooled and trapped\nat locations of purely circular polarization. The cooling process efficiently\naccumulates almost half of the atomic population in the lowest energy band\nwhich is only weakly coupled to the light field. Very low kinetic temperatures\nare obtained by adiabatically reducing the optical potential. The dynamics of\nthis process is analysed using a full quantum Monte Carlo simulation. The\ncalculations explicitly show the mapping of the band populations on the\ncorresponding momentum intervals of the free atom. In an experiment with\nsubrecoil momentum resolution we measure the band populations and find\nexcellent absolut agreement with the theoretical calculations.",
