ICRU Report 73, Stopping of Ions Heavier Than Helium


Following up on ICRU Reports 37 (Stopping powers for electrons and positrons) and 49 (Stopping powers and ranges for protons and alpha particles), this Report presents a critical survey on measurements and calculations of quantities governing the penetration of heavy ions through condensed and gaseous matter over an energy range from 1 keV/u upward.

The focus is on the electronic stopping force (or stopping power) for ions from lithium to argon
(Z1 = 3 – 18), but attention is also given to energy-loss straggling and, to a lesser degree, multiple scattering and ranges. Stopping tables are given for 17 ions on 25 elemental and 34 compound materials covering energies from 0.025 to 1000 MeV/u.
