Abstract
The transmission of positrons from 65Zn(Emax0.324 MeV) and 22Na(Emax0.544 MeV) in Be, Al, Cu, Ag, and Pb were compared with that of electrons of identical energies. The comparison of their mass absorption coefficients (μ/ρ) indicates a small but finite difference, implying greater transmission of positrons than electrons, with the exception of 0.324-MeV particles in Be and Al. These measurements were performed at atmospheric pressure. The results obtained clarify the existing ambiguity in the literature and are in agreement with multiple-scattering theory.
