just a few words about our background
25 March 1999
In the early eighties some people from
the University of Camerino participated to the first x-ray
absorption measurements collected at the national synchrotron
radiation (SR) facility (ADONE @
Laboratori Nazionali di Frascati) in
the framework of the PULS (Progetto per l'Utilizzazione della
Luce di Sincrotrone) project. These scientists were A. Bianconi,
S. Stizza and I. Davoli. Some more information about the development of
Physics at Camerino can be found
In the early 90s the activity was concentrated on the development of advanced "ab-initio" data-analysis methods (GNXAS) in collaboration with C. R. Natoli (Laboratori Nazionali di Frascati) and A. Filipponi (Universita` dell'Aquila) and on the performance of x-ray absorption measurements at international synchrotron radiation facilities (LNF and LURE).
In the 1990-1994 period the main research activities regarded:
1) development of computer codes (GNXAS) able to use multiple-scattering (MS) theory for X-ray absorption data-analysis. This has been a long-term project research conducted mainly by Filipponi and Di Cicco and inspired by Natoli who provided also the computer codes for phase-shift generation.
2) Application of MS theory for x-ray
absorption data-analysis in systems of known structure. Important
initial applications were on SiX4 molecules, brominated
molecules, bromine, silicon, iron.
3) Design and realization of XAS
measurements on liquid and supercooled metals. Study of local
two-atom and three-atom distributions in monoatomic liquids.
4) Absorption and photoemission study of
many-electron channels in core-level spectra.
5) XAS studies of High-Tc
superconductors and related compounds.
