The elementary particle called a muon is unstable and decays after 2.20 ?s, as observed in its rest frame, into an electron, a neutrino, and an antineutrino. What lifetime do you observe for the muon when it approaches you at 0.893 of the speed of light?
Briefly describe how the resulting interference pattern will differ for the various types of particles passing through: protons, electrons, neutrinos (mass close to zero) and photons. Assume that the distribution of particle energies is the same f..
