Table 13. Range and Energy Loss of Protons in Hydrogen and Helium 

 The following data were computed for hydrogen and helium at 0°C and 760 mm of 

 mercury from the Bethe stopping theory. Corrections for noncontributing shells, the 

 Fermi effect, and Brenisstrahlung are not included. Data calculated by W. Aron and 

 B. G. Hoffman, Radiation Laboratory, University of California, for the Atomic Energy
