Observation of Two Elastic Configurations at a Point Defect

A. J. Sievers, L. H. Greene

Research output: Contribution to journalArticlepeer-review


The anomalous temperature dependence of the impurity-induced far-infrared spectrum of KI: Ag+ indicates that at least two energetically inequivalent elastic configurations are simultaneously available to the defect-lattice system.
