Dependence of the nuclear recoil motion on the phonon spectrum of solids investigated by nuclear resonance fluorescence
European Physical Journal B(1984)
摘要
The time dependence of the recoil velocity of a140Ce nucleus in a La and a LaF3 lattice after ß emission is studied via the Doppler shift of the 1.596 MeV ? transition in140Ce. Evidence is obtained that the nucleus does not leave the lattice site even at a recoil energy of about 20 eV but carries out a damped oscillation. The quantitative comparison of the recoil velocity with the predictions of lattice theory leads to partial agreement.
