  "abstract": "We demonstrate experimentally that a single Rb atom excited to the $79d_{5/2}$ level blocks the subsequent excitation of a second atom located more than $10 \\mu\\rm m$ away. The observed probability of double excitation of $\\sim 30%$ is consistent with a theoretical model based on calculations of the long range dipole-dipole interaction between atoms.",
