Master singular behavior from correlation length measurements for seven one-component fluids near their gas-liquid critical point

International audienceWe present the master (i.e. unique) behavior of the correlation length, as a function of the thermal field along the critical isochore, asymptotically close to the gas-liquid critical point of xenon, krypton, argon, helium 3, sulfur hexafluoride, carbon dioxide and heavy water..
