Electron collision

  1. Oct 11, 2009 #1
    What happens when a negatively charged electron interacts with a positive proton, do they annihilate like electron and positron and produce photons? (i know they cant collide in an atom but if they were fired from opposite sides).

    Electrons and protons can merge into neutrons. That's what happens when a star collapses into a neutron star.

    Hi xmonty-
    Sometimes a proton in a radioactive nucleus can absorb an atomic electron, emit a neutrino, and become a neutron. This is called electron capture or K-capture. See
