摘要：

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