Abstract
Previous experiments have shown that in argon there exists a very good proportionality between the energy of an alpha-particle and the total ionization produced by it. In air this proportionality is not found, the ionization decreasing more rapidly than energy at low alpha-energies. Range-energy curves determined in the region 0-5 Mev, where the ionization in air is used as a measure of the alpha-energy, hence give too low energy values. Such curves, when corrected to equivalent ionization values in argon, show much better agreement with range and energy data derived from nuclear reactions. The range-energy curve for protons, derived from the alpha-curve, also shows improved agreement with nuclear data when the corrected alpha-range-energy curve is substituted for the old.
