Energy and emission

  1. May 24, 2012 #1
    Hello, I read that if an high energy electron impact with atoms some electron of the atoms can be emitted, does that happen with every high energy particle?
    For example, using an high energy proton instead of electron, will the opposite charges attract and reduce a bit the energy of the emitted electron?

    Thank you!

    I mean if protons and electrons attract themself, will this "attraction" energy be subtracted from the kinetic energy of the impact?
    If not, where does the attraction proton-electron came from and why it regards only that two praticles?

    Thank you!
