Description
The motion of atoms caused by neutrino emission following electron capture is observed in EuO crystals by measuring the Doppler shift of subsequently emitted gamma rays. The slowing down of the recoiling atom, which depends on the forces exerted by other atoms in the crystal, is calculated by molecular dynamics simulations using different interatomic potentials. The comparison between measured and simulated gamma-ray line shapes opens the way to a precise determination of the interatomic potential and of the lifetime of the nuclear state. copyright 1997 The American Physical Society
