Abstract : The dynamic properties of Ag+ dipole centers in RbCl single crystals were studied between 4 K and 50 K with the nuclear magnetic resonance method. The spin-lattice relaxation data of the nuclei 85Rb, 87Rb and 35Cl provide uniform correlation times of the localized motion of the < 110 > oriented Ag+ centers. The experimental data can be explained by a phonon-assisted orientational tunneling model recently proposed by Tonks and Dick.
