Cooperative coupling between optical emitters and light fields is one of theoutstanding goals in quantum technology. It is both fundamentally interestingfor the extraordinary radiation properties of the participating emitters andhas many potential applications in photonics. While this goal has been achievedusing high-finesse optical cavities, cavity-free approaches that are broadbandand easy to build have attracted much attention recently. Here we demonstratecooperative coupling of ultracold atoms with surface plasmons propagating on aplane gold surface. While the atoms are moving towards the surface they areexcited by an external laser pulse. Excited surface plasmons are detected vialeakage radiation into the substrate of the gold layer. A maximum Purcellfactor of $\eta_\mathrm{P}=4.9$ is reached at an optimum distance of$z=250~\mathrm{nm}$ from the surface. The coupling leads to the observation ofa Fano-like resonance in the spectrum.
