title: Local structure investigation of oxide ion and proton defects in Ge-apatites by pair distribution function analysis.
abstract: In this communication we provide a direct insight into the local structure and defects of oxygen excess Ge-apatites, in both dry and deuterated states, by means of pair distribution function analysis.
