We report the first on-line measurements of quadrupole-interaction-resolved nuclear magnetic resonance on oriented nuclei. The 10-min {sup 186}Au activity was obtained as daughter after cold implantation of mass-separated {sup 186}Hg into a hcp Co single crystal at the NICOLE facility at ISOLDE-3 (CERN). The quadrupole interaction of {sup 186}Au{ital Co}(hcp) was fully resolved, and the spectroscopic quadrupole moment of {sup 186}Au was determined to be {ital Q}=+3.12(20) b. This implies {beta}{sub 2}=+0.246(16), proving the large prolate deformation of the {sup 186}Au ground state.
