Local ordering in liquids under extreme conditions
CNISM-INFM, Dipartimento di Fisica, Universita\' degli Studi di Camerino
Abstract
Recent advances in data-analysis and instrumentation allowed us to perform x-ray absorption (XAS) studies of liquids, undercooled liquids and glasses under high-temperature and/or high-pressure conditions. The experimental set-up used for combined XAS and x-ray diffraction synchrotron radiation experiments at the ESRF will be briefly presented as well as equipments allowing preparatory experiments in our home laboratory. Advances in XAS data-analysis allowing detailed structural insight about pair and higher-order distributions will be also mentioned. Some recent applications to liquid and undercooled liquid metals
like Cu[1] and Sn will be presented.
