Popis:	The first prominent peak observed at s 1 in the total X-ray structure factors, S(s), of metaphosphate glasses containing the metal ions Li, Na, K, Ag, Ba, Sr, Cd, Pb, and of barium phosphate glasses with BaO mol% concentrations ranging from 2.5 to 56.5 has been studied to extract information on the intermediate range structure. The period, 2π/s 1 , of the quasi-periodic real-space electron density fluctuations is shown to be correlated with the ionic volume fractions of the glasses.
