摘要
The Li environment has been determined in a Lithium diborate glass by using neutron diffraction with isotopic substitution of Li. In the first difference function, oscillations are discernible up to 20 Angstrom(-1). Li appears in a strongly distorted tetrahedral site, with an average Li-O distance of 1.99 Angstrom second peak at 2.96 Angstrom is assigned to Li-B correlations and indicates dominant connections by corners between the Li polyhedra and the borate units.
