New results on WIMP-Xe-129 elastic scattering are presented. The target-detector is a pure liquid Xenon scintillator filled with Kr-free Xenon enriched in Xe-129 at 99.5%. Preliminary measurements with neutrons to estimate the quenching factor and to study a statistical pulse shape discrimination between electromagnetic background and recoils are also discussed.
