Gamma and photons

  1. Apr 12, 2005 #1
    Hi!

    I hope this is the correct section to post this question in.

    What's the difference betwen [tex]\gamma-decay[/tex] and photons?

    Thank you in advance.

    "Gamma decay",or gamma radiation is typically high energy (gamma(sic)) photons...

    [tex]\gamma[/tex]-rays are high-energy photons. [tex]\gamma[/tex]-decay is a type of radioactive decay in which [tex]\gamma[/tex]-rays are emitted.

    So basicly nothing, except that the [tex]\gamma[/tex] photons have more energy?

    Yeah,they're on the high-energy part of the spectrum.

    If I'm understanding you correctly, then the difference is that one is a type of decay and the other is a type of electromagnetic radiation. The [tex]\gamma[/tex] rays emitted in [tex]\gamma[/tex] decay are examples of photons, but they're a special type of photon (high-energy, as dexter pointed out).

    The term "gamma" for a photon dates back to the early days of experimental radioactivity. Three types of ray, behaving differentlly in a magnetic field, were observed. They were called alpha, beta, and gamma. The gamma rays, which were undeflected, were later found out to be photons. Lower energy photons had already been observed, since the sixth day of creation, as light.
