I Neutrons and strong interaction

  1. May 27, 2017 #1
    Is there any type interaction between neutron and matter other than strong interaction? When a neutron elastically or inelastically scattered, does the strong interaction still govern the whole process?

    Thank you!

    Does a neutron undergo electromagnetic interaction, due to having nonzero magnetic momentum?

    Weak interaction is, well, weak compared to electromagnetic interaction... but electromagnetic interaction of a neutron is also weak because of not having an electric monopole charge.

    What is the most important mechanism for elastic scattering between a neutron and an electron (which does not undergo strong interaction) - weak interaction, or electromagnetic interaction?

    Yes, but the effect is negligible.
    At low energies, both are negligible. At higher energies you get deep inelastic scattering, an interaction of the electron with a quark in the neutron.

    Yes, there are three more interactions. However, considering the interaction between a neutron and a nucleus, the effect of gravity is negligibly small.

    The electromagnetic interactions of neutrons are not negligible. They are important in electron neutron scattering, and proton neutron bremstrahlung.
