Pi-meson or also known as pion is one of any of the three (3) subatomic particles which characterizes of being unstable of its nature. The charged pions
π+
and
π−
decay with a mean lifetime of 26.033 nanoseconds or 2.6033×10−8 seconds, and the neutral pion
π0
decays with a mean lifetime of 84 attoseconds (8.4×10−17 seconds).
