Abstract
Systematic studies of the low-frequency Raman scattering (LFRS) in Na2 O-PbO-Bi2O3-P2O5 phosphate glasses have been undertaken. In the contin uum media approximation, these studies, permit one to find out the str uctural correlation range R-c, and to determine the structural correla tion function. The estimated correlation lengths from the LFRS support s the concept that the scale for structural order in the studied glass es is similar to 7 Angstrom.
