Zusammenfassung: 
Atomic environment of xFe(2)O(3) (.) (80 - x)Bi2O3 (.) 20Ga(2)O(3) heavy glasses (0 less than or equal to x less than or equal to 20 mol%) was investigated with respect to electronic structure of the samples. Data obtained from Bi 4f, Ga 2p, Fe 2p, and O 1s core-level photoelectron spectra indicate changes in the local order on the account of partial substitution of bismuth by iron. The bismuth cations behave essentially as network formers while the iron and gallium ones acts as network modifiers. The number of nonbridging oxygens depends on Fe2O3 content.
