Muon capture
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 involves capture of a negative muon from the atomic orbital without emission of a gamma photon:
Radiative muon capture is a radiative version of OMC, where a gamma photon is emitted:
One motivation for the study of muon capture on the proton is its connection to the proton's induced pseudoscalar form factor gp.
