摘要：

Low-energy background spectra from 1.3 kg and 6.2 kg Nal(Tl) crystal scintillators operating in the shielded Boulby underground facility were measured. Upper Limits to the scattering interaction rates and cross-sections of Galactic dark matter in the form of Weakly Interacting Massive Particles (WIMPs) are calculated from these data. This work provides an improved limit for spin-dependent interactions for WIMP masses above 10 GeV.
