Energy from proton and antiproton

  1. Dec 20, 2005 #1
    Is there a set wavelength for photons produced from antimatter reacting its matter equivalent, and if there is, what wavelength does a proton and antiproton reacting create?

    There is no fixed wavelength for this, since it depends on the total energy of the original particles, which can be much larger than their mass-energy equivalent.

    I seem to remember most [itex]p\bar{p}[/itex] reactions yielded cascades of mesons, with high sufficiently high energy protons producing baryonic resonances (hyperons) which decayed to protons and mesons, or pi-meson cascades. The mesons (charged pions) would decay to muons, which would decay to electrons, and I am leaving out the various neutrinos and anti-neutrinos.

    Also, pions can interact with protons and neutrons producing Kaons and other baryonic resonances.

    Generally, gamma rays are associated with [itex]\pi^o[/itex] decay and positron annihilation.
