1.7.1.1 Electron irradiation

Abstract

This chapter deals with production of atomic defects in pure polycrystalline metals. Theoretical calculations indicate a significantly lower cross section for defect production by positrons than by electrons. For metals which show annealing already around 4.2 K, the irradiation temperature is indicated in a table. In the case of mercury, a strong temperature dependence of damage rate was observed between 3.0 K and 5.7 K. Curved damage rates vs. dose dependences were also observed in alkali metals (Li, K, Na) under 3MeV electron irradiation. Extrapolation of the electron damage rate curves to low energies is the most common method to determine displacement energy. Data of displacement energies under electron irradiation at temperature from resistivity measurements, from transmission electron microscopy on loops, on voids, and from magnetization measurements are tabulated. The chapter also lists resistivities per unit concentration of Frenkel pairs.
