A pion at rest (mp 5 273me) decays to a muon (mm 5 207me)
Chapter 39, Problem 61(choose chapter or problem)
A pion at rest (mp 5 273me) decays to a muon (mm 5 207me) and an antineutrino (mn < 0). The reaction is written p2 S m2 1 n. Find (a) the kinetic energy of the muon and (b) the energy of the antineutrino in electron volts.
