Experimental Test of Quantum Electrodynamics by Muon Bremsstrahlung

Abstract

We have measured muon bremsstrahlung of 9- to 13-GeV/c muons by using a carbon-plate spark chamber as a target. Our results in the region of invariant four-momenta of the recoil muon-photon system 200-650 MeV/c are consistent with the predictions of quantum electrodynamics.
