The p0 meson is a particle that has a rest energy of 135.0 MeV (see Table 32.3). It lives for a very short time and then decays into two g-ray photons: p0 B g 1 g. Suppose that one of the g-ray photons travels along the 1x axis. Concepts: (i) How is the energy E of each g-ray photon related to the rest energy E0 of the p0 particle? (ii) How can the frequency and wavelength of a photon be determined from its energy? (iii) How is the total linear momentum of the photons related to the momentum of the p0 particle, and what is the momentum of each particle? Calculations: If the p0 is at rest when it decays, fi nd (a) the energy (in MeV), (b) the frequency and wavelength, and (c) the momentum of each g-ray photon.
