Muon capture is the capture of a negative muon by a proton, usually resulting in production of a neutron and a neutrino, and sometimes a gamma photon. Muon capture by heavy nuclei often leads to emission of particles; most often neutrons, but charged particles can be emitted as well. Ordinary muon capture (OMC) involves capture of a negative muon from the atomic orbital without emission of a gamma photon: μ- + p+ → nu + n Radiative muon capture (RMC) is a radiative version of OMC, where a gamma photon is emitted: μ- + p+ → nu + n + γ One motivation for the study of muon capture on the proton is its connection to the proton's induced pseudoscalar form factor gp.
