    "abstract": "We experimentally study the motion of atoms interacting with a periodically\npulsed near resonant standing wave. For discrete pulse frequencies we observe a\ncomb-like momentum distribution. The peaks have widths of 0.3 recoil momenta\nand a spacing which is an integer multiple of the recoil momentum. The atomic\npopulation is trapped in ground states which periodically evolve to dark states\neach time the standing wave is switched on.",
