Description
The highly radiopure about 250 kg NaI(Tl) DAMA/LIBRA set-up is
running at the Gran Sasso National Laboratory of the I.N.F.N..
Here first results obtained by this second generation experiment
exploiting the model independent annual modulation signature for Dark
Matter particles in the galactic halo are presented (exposure of
0.53 ton x yr).
DAMA/LIBRA data confirms the presence of Dark Matter particles in
the galactic halo firstly pointed out by DAMA/NaI.
The combined analysis of the data of the two experiments
(total exposure 0.82 ton x yr) gives a C.L. at 8.2 sigma.
