The extrapolated rangeRexand the projected rangeRprof 4‐ to 24‐MeV electrons in Be, Al, Cu, Ag, and Au have been determined from the experimental data for the charge‐deposition distribution produced by the electrons in the effectively semiinfinite absorber. While the results forRexshow no significant difference from the data obtained by Harder and Poschet and by Ebertet al.for the absorber configuration of finite slab, the present values ofRprfor the absorbers of high atomic number are slightly smaller than the results of Harder and Poschet. In the energy region considered here,Rexhas been found to obey an empirical equation of the formRex=A(E0−B)C, whereA, B, andCare expressed by simple functions of atomic number, andE0is the incident kinetic energy of the electron. A semiempirical relation previously found betweenRprand the continuous slowing‐down approximation rangeR0has been modified so as to show a better agreement with the present data.
