RT Journal Article T1 Antonella: A nuclear-recoil ionization-efficiency measurement in 2 silicon at low energies A1 Molina Insfrán, Jorge Andrés A1 Izraelevitch, F. A1 Amidei, D. A2 Universidad Nacional de Asunción - Facultad de Ingeniería A2 Universidad de Buenos Aires (AR) A2 University of Michigan (US) AB We have measured the ionization efficiency of silicon nuclear recoils with kinetic energy between 1.8 and 20 keV. We bombarded a silicon-drift diode with a neutron beam to perform an elastic-scattering experiment. A broad-energy neutron spectrum was used and the nuclear recoil energy was reconstructed with the time-of-flight technique. The overall trend of the results of this work are well described by the theory of Lindhard et al. above 4 keV of recoil energy. Below this energy, the presented data shows a deviation from the model. The data indicates a faster drop than the extrapolation of the Lindhard theory to low energies.
