| dc.description.abstract | <p> The mean square displacement spectrum of a single mass defect and that of its neighbours is examined for both a light and a heavy defect to observe the extent of the perturbation of the pure crystal. </p> <p> Nearest neighbour force constant changes for a 3% random distribution of gold defects in a copper host are calculated by fitting to experimental elastic constants for this alloy. The phonon shifts and widths are calculated for the system with various sets of force constant changes, and comparison is made with experiment. </p> | en_US |
