Muon lifetime
Muon lifetime is the average time a free muon exists before decaying into other particles, such as an electron and neutrinos.

Both timelines start together. Length measures elapsed time, not a physical distance.
A little perspective
The lifetime of a muon is about 22 times 100 nanoseconds.

Muon lifetime
Mean lifetime: 2.197 µs; measured; range 2.197 µs–2.197 µs.
A free positive muon has a mean lifetime of about 2.197 microseconds before decay. This is a statistical mean, not an identical lifetime for every muon.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 2.197 µs for the lifetime of a muon; the recorded range is 2.197 µs–2.197 µs.
- The lifetime of a muon: This is a measured value; check the notes for its source and scope.
