Accurate EXAFS spectra of solid and liquid rhodium at very high temperature were recorded at the E.S.R.E (BM29, Grenoble) The short range g(r) was determined using reliable EXAFS data-analysis methods based on ab-initio multiple scattering calculations. Experimental results were compared with moleculardynamics (MD) calculations. The first neighbor distribution departs from a simple Gaussian model, even at moderate temperatures in the solid phase.
