Abstract
We report recent results of a WIMP dark matter search experiment using 310 g of CaF2(Eu) scintillator at Kamioka Observatory. We chose a highly radio-pure crystal, PMTs and radiation shields, so that the background rate decreased considerably. We derived limits on the spin dependent WIMP-proton and WIMP-neutron coupling coefficients, ap and an. The limits excluded a part of the parameter space allowed by the annual modulation observation of the DAMA NaI experiment.
