A total effective exposure of 384 kg d has been achieved, mostly coming from fourteen months of continuous operation. Five nuclear recoil candidates are observed above 20 keV, while the estimated background is 3.0 events. The result is interpreted in terms of limits on the cross-section of spin-independent interactions of \WIMPs\ and nucleons. A cross-section of 4.4 × 10 − 8   pb is excluded at 90%CL for a \WIMP\ mass of 85 GeV. New constraints are also set on models where the WIMP-nucleon scattering is inelastic.
