scope:

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 â€" 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.
