If a particle is in a stationary state, does that mean that the particle is not moving? If a particle moves in empty space with constant momentum p → and hence constant energy E = p2/2m, is it in a stationary state? Explain your answers.

- A charged pion & (π‡), an unstable particle of mass 140 MeV/c², is known to decay into a muon (μ‡, mass 106 MeV/c²) and a neutrino (1; we can treat it as massless here). In this decay of pion (→ + ₁), typically only the muon is detected, the neutrino being an electrically neutral particle that rarely interact with other matter. Properties of neutrinos in this decay are inferred from measured properties of pion and muon. Explain, as conceptually as possible, why it is not possible for a pion to simply decay into a muon, without an associated neutrino. That is, why is this decay, π → Mt, impossible? (Note: If you happen to know about lepton numbers and neutrino flavors, please give an explanation that does not make use of concepts we have not yet covered.)arrow_forwardThe K+ meson, a subatomic particle, has an average rest lifetime of 1.0 x 10-8 s.

The wavelengths of visible light stretches from 2A = 400 nm to ig = 700 nm, approximately. Ans.: -0.22 < Bß<0.33arrow_forward
- A linear particle accelerator using beta particles collides electrons with their anti-matter counterparts, positrons. The accelerated electron hits the stationary positron with a velocity of 98 x 106 m/s, causing the two particles to annihilate.If two gamma photons are created as a result, calculate the energy of each of these two photons, giving your answer in MeV (mega electron volts), accurate to 1 decimal place. Take the mass of the electron to be 5.486 x 10-4 u, or 9.109 x 10-31 kg.Note: Assume that the kinetic energy is also converted into the gamma rays, and is included in the two photons.arrow_forwardThe muon is an unstable particle that spontaneously decays into an electron and two neutrinos.
