Local Order in Hydrogenated Amorphous Germanium Thin Films (1997)
Dalba, G., Fornasini, P., Graeff, C., Grisenti, R., Rocca, F., Traverse, A.
The effect of the hydrogenation process on the local order in amorphous germanium has been studied by EXAFS spectroscopy. Measurements have been carried out on amorphous sputtered Ge:H films with 7,...
Temperature Dependent Re L3-Edge X-Ray Absorption Study of Crystalline Rhenium Trioxide ReO3 (1997)
Kuzmin, A., Purans, J., Dalba, G., Fornasini, P., Rocca, F.
X-ray absorption spectroscopy study of crystalline ReO3 was performed at the Re L3-edge in the temperature interval from 77 to 670 K. The analysis of both XANES and EXAFS regions shows that in ReO3,...
Non gaussian distributions in disordered systems studied by the cumulant expansion of EXAFS (1992)
Dalba, G., Fornasini, P., Rocca, F., Sadoc, A.
To test the effectiveness of the cumulant method for asymmetric distributions we measured and analyzed EXAFS in the anharmonic compound [MATH]-AgI from 23 to 410 K. The physical consistency of the so...
EXAFS STRUCTURAL STUDIES OF AROMATIC POLYMERS/RUTHENIUM CATALYSTS (1986)
Dalba, G., Fornasini, P., Rocca, F., Pertici, P., Burattini, E.
The coordination of ruthenium in polystyrene/ruthenium catalysts has been studied by EXAFS. Ru atoms result complexed to the phenyl rings and tend to group in small clusters. The extent of the...
XANES IN FAST ION CONDUCTING GLASSES AgI : Ag2O : B2O3 (1986)
Dalba, G., Fornasini, P., Rocca, F ., Burattini, E .
The XANES at the Ag L edges of glasses Ag2O : B2O3, analyzed in terms of electronic transitions to unoccupied molecular orbitals, confirm previous EXAFS results and support a model for the bond...
XAS STUDIES ON THE ROLE OF THE ALKALINE ION IN A LEAD-GLAZE SYSTEM (1986)
Dalba, G., Fornasini, P., Rocca, F., Krajewski, A., Ravaglioli, A., Burattini, E.
The influence of the local coordination on the Pb++ mobility has been studied by EXAFS in Lead-glaze systems with different modifier oxides. The interatomic distances and coordination numbers...
SHORT RANGE ORDER IN SILVER BORATE GLASSES (1985)
Dalba, G., Fornasini, P ., Rocca, F.
The coordination of the silver cation in the glasses Ag2 O n B2O3 has been studied by EXAFS. The values of coordination number (N≈2) and Debye-Waller factor denote an high degree of short range...
