BACKSCATTERING COEFFICIENTS OF ELECTRONS: A REVIEW

The experiment on the backscattering coefficient of electrons of energies from 3.2 to 14 MeV, published in 1967 by the present author, is reviewed to confirm the usefulness of its results as a benchmark for Monte Carlo calculations. The cause of large discrepancies between Dressel’s and other results is described. Comparisons of compiled experimental data and results of Integrated TIGER Series Monte Carlo Code System are cited and discussed. In Appendix, experimental data of the present author’s group on the charge deposition profile of electrons are mentioned as another useful benchmark. 1
