Noun

muon (plural muons)

1. (physics) An unstable elementary particle in the lepton family, having similar properties to the electron but with a mass 207 times greater.
   • 1951, Enrico Fermi, Elementary Particles:

     The μ-meson of Powell (called here muon) is instead a disintegration product of the pion, only weakly linked to the nucleons and therefore of little importance in the explanation of nuclear forces.

   • 1955 March, CP Sargent, “Diffusion Cloud-Chamber Study of Very Slow Mesons”, in Physical Review:

     The spectrum of electrons arising from the decay of the negative mu meson has been determined. The muons are arrested in the gas of a high pressure hydrogen filled diffusion cloud chamber.

Derived terms

• muogenic
• muonic
