Abstract

We have utilized the electron-capture decay of119 Te to119Sb to produce isolated single Frenkel pairs in InSb. This effect is caused by the neutrino emission in the decay process which imparts a monoenergetic recoil of 12 eV to the119Sb atoms, thereby displacing about 20% of them to interstitial sites. Two distinct interstitial components can be observed. The process is traced by Mössbauer emission spectroscopy following the decay of119Sb to119Sn. The displacement thresholdEd is confined to 6 eV<Ed <12 eV from auxiliary experiments employing119mTe isotopes.
