muon (μ)
subject			fact

muon	has symbol μ
	has charge -1
	has definition A second-generation lepton. It is essentially a more massive electron.
	has definition Short-lived elementary particle with negative electrical charge. Muons are leptons. They resemble electrons, but are 207 times more massive.
	has definition An elementary particle, formerly called a mu-meson but now classified with the leptons because it seems to be identical with the electron except for its much greater mass (207 times that of an electron). The muon family includes the muons and their neutrinos (and their antiparticles). Muons may have a positive or a negative charge.
	has definition Elementary particles produced when cosmic rays enter the upper atmosphere.
	is an instance of lepton
	is an instance of radioactive particle
	is an instance of charged particle
lepton	has spin 1/2
radioactive particle	has desintegration energy the total energy produced when the particle decays
	has decay products the products produced immediately after decay
	has lifetime The average time in which a particle decays
charged particle	is accelerated by electric or magnetic fields
fermion	has quantum behavior Fermi-Dirac statistics
	obeys exclusion principle
particle	obeys uncertainty principle
	has frequency inversely proportional to the wavelength
	has wavelength inversely proportional to its momentum
	has mass
physical object	has location or center of gravity
	has angular momentum
	has velocity
	has momentum
	has temperature
	has volume
	has extent
	has material
