Description

The authors studied elastic and inelastic scattering of dark matter with nuclei in huge NaI(Tl) scintillator. The light output response f was measured by fast neutron scattering. The result was fI=0.05±0.02 for I recoil and fNa=0.4±0.2 for Na recoil. The low noise ( similar eq5keV) and low BG ( similar 8counts/day/keV/kg) was achieved by huge (36.5kg/module) NaI(Tl) scintillator. Strong limit for inelastic excitation of 127I nuclei was studied and strong limit on the local halo density of spin coupled dark matter candidate was derived. ((orig.))
