REFINING STRUCTURAL MODELS FOR GLASSES : IS IT POSSIBLE ? THE CASE OF ” Pb 2 M 2 F 9 ”
semanticscholar(2018)
摘要
A method allowing the fit of interference functions by a least square refinement of atomic positions in a quasicrystalline starting model is presented. Application is made on "Pb,M,F," fluoride glasses. The crystalline KPbCr,F, structure appears to give a good possible description of the mean local organization in these glasses.
