Measurement of the stopping power for ?? and ?+ at energies between 3 keV and 100 keV

Abstract

An experiment has been performed to measure the stopping power of carbon, gold and magnesium fluoride for μ− and μ+ at energies between 3 and 100 keV. The energy loss of negative and positive muons was determined by measuring their time of flight in front of and behind a target. For these measurements a parallel plate avalanche counter and a microchannel plate were used. The Bragg peak has been observed. The Barkas effect was measured down to two times the Bohr velocity.
