Abstract
Direct observations of Cs-intercalated, highly oriented pyrolytic graphite (HOPG) exposed to neutron irradiation show that the presence of Cs dramatically enhances the radiation-induced dimensional changes. A qualitative explanation of this behavior employs an island domain or “pleated layer” model of the graphite intercalation compound (GIC) structure. The inferences from this model are consistent with earlier data for neutron-induced dimensional changes in oriented pure graphite as a function of crystallite size.
