Proton Velocity

  1. Jul 22, 2015 #1
    Is there a standard velocity for a proton when and if it is released from an atom?

    No, it depends on the process, how it is released, but what kind of process do you have in mind?

    Either by fission, or by proton bombardment that displaces existing protons from the target atom. Thanks for the reply.

    But think about it. Assuming that you have some knowledge of photoelectric effect, can't you see a similar phenomenon here? I can shoot protons (or neutrons, etc) of varying energies at an atom. Such energies will be used to liberate the protons in the atoms, but depending on the collision, the protons will also take various fractions of the primary proton energy for their kinetic energy. This results in a spectrum of proton energies.

    So why would there be only one "standard" velocity or energy of such outgoing protons?

    I thought perhaps there might be a constant or a proposed theory or real data about the limits on the velocity of proton emission.

    Read your original post again. You said no such thing.

    The limit to the proton velocity is c.

    Yes there is a limit to the energy of the proton and it depends on the process's energy release and the products' masses...
