NMR study on ionic transport in silver halides
Abstract The temperature dependence of 1/ T 1 , for 23 Na, 35 Cl, 79 Br and 81 Br in AgX and NaX ( X = Cl , Br ) has been measured from 77 K to 700 K, and the results of AgX are compared with those of NaX. With the Bloembergen-Purcell-Pound model, we obtain the activation energies from which the effective radius of the mobile Ag + ion is evaluated to be of the order of 1 A.
