摘要:

Using electrical resistivity measurements the recovery of pure lead irradiated at low temperature with electrons has been investigated from 3 K up to 340 K as a function of electron dose and energy. Doping experiments have also been performed. The annealing behaviour of lead is similar to other fcc-metals, except gold. The recovery stage I at about 4 K (first reported by Birtcheret al.6clearly shows the separation of IDand IEdue to the correlated and un-correlated annealing of interstitials. After stage II (5 K to 120 K) the dose dependent recovery stage III has been observed at about 160 K. In this region the single-vacancies should migrate and anneal with an activation energy Qm1v= 0.43 ± 0.03 eV determined by the “change of slope” method. In the last recovery stage usually called stage V at about room temperature vacancy clusters should dissolve. The measured activation energy of this process is about 1.05 eV which is equal to the self-diffusion energy in lead.
