WebMuons have a mass of 105.66 MeV/ c2, which is approximately 206.768 2830(46) [6] times that of the electron, me. There is also a third lepton, the tau, approximately 17 times heavier than the muon. Due to their greater mass, muons accelerate slower than electrons in electromagnetic fields, and emit less bremsstrahlung (deceleration radiation).
