Muon
[myoo-on] /ˈmyu ɒn/
noun, Physics.
1.
a lepton similar in most respects to the electron except that it is unstable, it may be positively charged, and its mass is approximately 207 times greater; the positively charged muon is the antiparticle of the negatively charged muon. Symbol: μ.
/ˈmjuːɒn/
noun
1.
a positive or negative elementary particle with a mass 207 times that of an electron and spin 1/2. It was originally called the mu meson but is now classified as a lepton
muon
(my’ŏn’)
An elementary particle in the lepton family having a mass 209 times that of the electron, a negative electric charge, and a mean lifetime of 2.2 × 10-6 seconds. The muon was originally called the mu-meson and was once thought to be a meson. See Table at subatomic particle.

noun 1. (physics) an experimental form of nuclear fusion in which hydrogen and deuterium muonic atoms are formed. Because the mass of the muon is much larger than that of the electron, the atoms are smaller, and the nuclei are close enough for fusion to occur
