Abstract: (Elsevier)
This paper gives tables of material properties needed for the evaluation of the collision stopping power for electrons and positrons according to the Bethe theory. The key quantity is the mean excitation energy of the medium, which has been derived for many materials by a critical analysis of experimental data. Also given are the density-effect parameters of the theory of Sternheimer and Peierls. The material properties are given for the elements and for 180 compounds and mixtures, and the rules are described by which they could be obtained for other materials. Tables are also given of auxiliary quantities which depend only on the kinetic energy of the incident electron. These, together with the main tables, make possible the quick-and-easy evaluation of the collision stopping power.
