چکیده
We estimate terrestrial antineutrino and neutrino fluxes according to different models of Earth composition. We find large variations, corresponding to uncertainties on the estimated U , T h and K abundances in the mantle. Information on the mantle composition can be derived from antineutrino flux measurements after subtracting the crust contribution. This requires a good description of the crust composition in the region of the detector site. Measurements of terrestrial antineutrinos will provide a direct insight on the main sources of Earth's heat flow.

Complementary measurements have been performed for the level density and γ strength function in 162 Dy using inelastic 3 He scattering. Comparing these results to previous measurements using the 163 Dy(3 He,α) reaction , reveals that the measured quantities above 1.5 MeV do not depend significantly on the nuclear reaction chosen.
