We have used nuclear-quadrupole-resonance (NQR) techniques to study Cu nuclei in two single-crystal samples of CeCu{sub 6} between 200 {mu}K and 20 mK. We present measurements of the NQR intensities and spin-lattice relaxation times, {ital T}{sub 1}, at frequencies corresponding to three different sites in the crystal. Below 5 mK we observe deviations from standard metallic behavior in both signal intensity and spin-lattice relaxation times. These deviations are unusual in that they are site dependent; they reveal the presence of one or more types of order in this system.
