Abstract
Cross relaxation between implanted positive muons and Al-27 nuclei in Al metal, lightly doped with Cu to impede the muon diffusion, shows we ak resonances at 2.3 and 4.0 mT. Assignment of these to polarization t ransfer via the 1/2 <-> 3/2 and 3/2 <-> 5/2 transitions of the (J = 5/ 2) spins leads to a quadrupole coupling constant e2qQ/h = 1.8(1) MHz, i.e. an electric field gradient on Al nuclei immediately adjacent to t he muon site q = 0.048(3) a.u., with a small departure from axial symm etry.
