Muon - Wikipedia It is classified as a lepton As with other leptons, the muon is not thought to be composed of any constituent particles The muon is an unstable subatomic particle with a mean lifetime of 2 2 μs
What are muons and where do they come from A muon is an elementary particle that is very similar to an electron, but much more massive than it It was discovered in the first half of the twentieth century and was initially suspected to be something else entirely
DOE Explains. . . Muons | Department of Energy The muon is one of the fundamental subatomic particles, the most basic building blocks of the universe as described in the Standard Model of particle physics Muons are similar to electrons but weigh more than 207 times as much
About Muons – MuonSources The muon technique involves implanting spin-polarised positive muons into a material, where they undergo decay and release positrons The positrons are analysed to understand the muon’s behaviour inside the material – particularly how the muon polarisation changed within the sample
Muons - Lawrence Berkeley National Laboratory A muon interacts very little with matter except by ionization Because of this, muons can travel large distances and commonly reach the ground However, they lose energy proportional to the amount of matter they pass This is proportional to the density (g cm 3) times the path length (cm)
Muons: The Subatomic Particles Shaking Up the World of . . . That would be the muon, a particle first discovered in the late 1930s, which is formed in nature when cosmic rays strike particles in our planet's atmosphere Muons are passing through you and everything around you at a speed close to that of light
