A comparison of the calculational methods used here and in other recent proton range-energy tables is presented in Table 14. Keys for the references used for each element are collected in Table 12. The literature search was completed in June 1979. The straggling calculations include electronic, elastic nuclear, and charge exchange effects. Ranges were obtained by use of multiple Coulomb scattering theory. Path- lengths were calculated by integrating the reciprocal of the energy losses. The polarization effect was calculated in detail for each material. New values of the adjusted ionization potentials were determined by least-squares-fitting the Bethe equation to all available energy-loss data. Above 1.0 MeV, the Bethe equation with all necessary corrections was used. The energy loss between 20 keV and 1.0 MeV was obtained by statistically evaluating the accuracy of the available experimental information and then performing least-squares curve fits. The energy loss below 20 keV was found by normalizing theoretical expressions for the ionization, excitation, and nuclear contributions to known values at 20 keV. The accuracies of all proton range-energy parameters are tabulated. Emphasis has been placed on obtaining accurate results, par- ticularly in the: difficult low-energy and high-atomic-number regions. JANNI* Air Force Weapons Laboratory (NTYC) Kirtland Air Force Base, New Mexico Extensive tables have been prepared of the mean energy loss, pathlength, range, multiple scattering, patlhlength straggling, time-of-flight, and nonelastic collision probability for protons of energy from 1 keV through 10 GeV in all elements having atomic number from 1 through 92, and in many compounds and mixtures.
