The critical scattering universal function measured through sans: An experimental test of the scaling laws

Recent measurements of the critical scattering from a simple-liquid system (Xenon) by means of small-angle neutron scattering (SANS) are reported. A study of the critical scattering function g(q~) was performed, leading to a determina- tion of the critical indices and a test of the validity of the scaling hypothesis. Here we report the results of the preliminary data analysis.
