A Muon is an elementary particle similar to the electron, with an electric charge of ?1 e and a spin of 1/2 but 207 times heavier. A muon is an unstable subatomic particle with a mean lifetime of 2.2 ?s which is much longer than many other subatomic particles. It has two forms, the negatively charged muon and its positively charged antiparticle. Muons do not emit as much bremsstrahlung (deceleration radiation) as electrons, which are the primary reason electrons decelerate and this allows muons of a given energy to penetrate far more deeply into matter than electrons. Muons were discovered by Carl D. Anderson and Seth Neddermeyer at Caltech in 1936. Its existence was however confirmed only in 1937 by J. C. Street and E. C. Stevenson's cloud chamber experiment. Muons arriving on the Earth's surface are created indirectly as decay products of collisions of cosmic rays with particles of the Earth's atmosphere.
