| Summary: | Emission of positive muons (μ⁺) of low kinetic energy, with yield peaked at 5 to 20 electron volts and slowly decreasing to higher energy, has been observed by moderating
a muon beam (p~28MeV/c, Δp/p~4%) with solid argon, krypton and xenon moderators. Emission at these energies is consistent with the muons escaping the target
material still carrying part of their initial kinetic energy. The underlying cause of this enhancement of low energy positive muons is not determined. Variation of charge-exchange, elastic or inelastic collision cross sections with energy, resulting in an increased charged fraction or greater mean free path for muons at these energies, are possible causes. === Science, Faculty of === Physics and Astronomy, Department of === Title page of the thesis missing. === Graduate
