Abstract

We have measured the ionization produced in a Si(Li) detector by silicon nuclei of kinetic energies in the range 3.2-21 keV. The results are in rather good agreement with the calculations of Lindhard, Scharff, and Schiott and demonstrate the interest of Si(Li) detectors for dark-matter searches. We have also measured the intrinsic fluctuations in the ionization energy due to nucleon recoils.
