Abstract

Graphite intercalation compounds have been studied by positron annihilation experiments. In donor compounds, a highly inhomogeneous charge distribution is detected by Coulomb repulsion of the positrons from the intercalant. In acceptor compounds, however, quasifree positron-anion systems are formed within the intercalant. This is used to identify the anionic species.
