Neutron captured by Proton

  1. Jul 19, 2011 #1
    I refer to the last paragraph of http://physicsworld.com/cws/article/news/46592

    quote: A few hundred milliseconds later, the neutron is captured by a proton to form a deuteron

    Can someone please explain how a proton captures a neutron or provide links to articles describing this

    To elaborate a little more, it looks to me like the neutrinos interact with the protons of the Hydrogen that composes part of the mineral oil. Turning this lone proton into a neutron effectively "destroys" that atom, for lack of a better term, and the neutron is now a free neutron. It itself is has kinetic energy and is captured by another Hydrogen atom in the oil, resulting in the formation of Deuterium.

    As to HOW the neutron is captured, that is simply because of the Strong force: http://en.wikipedia.org/wiki/Strong_force
