Extrapolated and projected ranges of electrons in metals

摘要

The extrapolated range Rex and the projected range Rpr of electrons in metal absorbers have been calculated using the Wilson expression for mean range of high‐energy electrons. The results are in good agreement with experimental values reported by Tabata, Ito, and Okabe [J. Appl. Phys. 42, 3361 (1971)]. Schematic comparison of the calculated values with experimental data is made.
