Abstract

We show how ultra high resolution (n, γ ) spectroscopy can be used to determine lifetimes of nuclear excited levels through the observation of Doppler broadening of deexciting transitions. This Doppler broadening is induced by the recoil imparted by feeding transitions and allows the study of lifetimes −11 s.
