The decay of 119Te to 119Sb via electron capture was used to produce isolated single Frenkel pairs. This was caused by neutrino emission, which imparted a recoil of 12eV to the 119Sb atoms; thereby displacing about 20% of them into interstitial sites. The effect was monitored by using Mössbauer emission spectroscopy to follow the decay of 119Sb into 119Sn. By performing auxiliary experiments, using 119mTe isotopes, the displacement threshold was estimated to be between 6 and 12eV.
