| Abstract: | 111Cd–PAC measurements have been made using the high specific activity of 111In in the methanol–water mixtures of various concentrations at the room temperature. These experiments revealed that the perturbation factors 〈A 2 G 2〉 (integrated over two mean lives τN) do not follow the dependence of the macroscopic viscosity η. The observed dynamic character of the PAC spectra in ice is explained by the mobility of orientational and ionic defects. The activation energy for the diffusion process was determined to be E a =0.35(1) eV. This revised version was published online in September 2006 with corrections to the Cover Date. |
