Abstract
We report results of a measurement with 15 superheated droplet detectors of total active mass 0.208 kg, comprising the first stage of a Phase II experiment. In combination with the results of the neutron-spin sensitive XENON10 experiment, these results yield a limit of for on the spin-dependent sector of weakly interacting massive particle-nucleus interactions with a 50% reduction in the previously allowed region of the phase space, formerly defined by XENON, KIMS, and PICASSO. In the spin-independent sector, a limit of at is obtained.
