Abstract
The Structure and the location of deuterium atoms were investigated for the deuterated nano-graphite by neutron diffraction. The deuterated nano-graphite was prepared by mechanical milling under deuterium gas atmosphere. The structure of graphite was changed by a creation of dangling bonds and deuterium was absorbed by the solid-gas reaction when the milling proceeds. The RDF(r) observed by neutron diffraction indicates two kinds of locations of deuterium atoms, that is, some deuterium atoms bond with the carbon atoms and others exist between layers of the graphite.
