Abstract
The atomic mean-square displacement (MSD) of granular tin was studied by the Mössbauer effect. Tin grains with a 45-Å average size embedded in an oxide matrix were produced by evaporating the metal in the presence of . The lattice parameters and grain-size distribution were measured by electron microscopy. From the temperature variation of the MSD of the granular material, it was found that the moment of the phonon spectrum increases by (8±3)% with respect to the bulk. These results, combined with data of the hyperfine constants and electron microscopy suggest a quasi-isolated grain whose vibration frequency and electronic structure are barely altered and whose interaction with the surrounding oxide is negligible.
