muon
- n an elementary particle with a negative charge and a half-life of 2 microsecond; decays to electron and neutrino and antineutrino
- Be cause the muon leaves a wake of ionized gas, which conducts electricity, a spark will jump between each pair of plates along the path of the particle.
- One clue was the detection of a muon, a close relative of the electron.
- Aimed beyond the earth's atmosphere, a muon beam would be bent down toward the surface again by the earth's magnetic field and could be detected hundreds of miles from its point of .
