We measured the nuclear-recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from monoenergetic beam scatter off of nuclei at angles corresponding to energy depositions 4 keV down 100 eV, lowest probed so far. The results show no sign an production threshold above eV. These call for further investigation theory and comprehensive determination detector response function energies below scale.
