The electron-capture decay of 119Te to 119Sb was used to produce isolated single Frenkel pairs. This effect was caused by neutrino emission in the decay process, which imparted a mono-energetic recoil of 12eV to the 119Sb atoms and thus displaced some 20% of them into interstitial sites. The process was monitored by using Mössbauer emission spectroscopy, following the decay of 119Sb to 119Sn. The displacement threshold was deduced to be between 6 and 12eV, on the basis of experiments which involved 119mTe isotopes.
