SUMMARY

The discussion centers on the process of neutron capture by a proton, leading to the formation of deuterium. It highlights that a neutron, after being freed from its original atom, possesses kinetic energy and is subsequently captured by a proton from hydrogen. This interaction is governed by the strong force, which is the fundamental force responsible for binding protons and neutrons in atomic nuclei. The reference to the article from Physics World confirms the timeline of this capture occurring a few hundred milliseconds after the neutron is freed.

PREREQUISITES
  • Understanding of nuclear physics concepts, specifically neutron and proton interactions.
  • Familiarity with the strong force and its role in atomic structure.
  • Basic knowledge of deuterium and its formation from hydrogen.
  • Awareness of neutrinos and their interactions with protons.
NEXT STEPS
  • Research the mechanics of the strong force in nuclear interactions.
  • Explore the process of neutron capture in various isotopes.
  • Study the role of neutrinos in nuclear reactions and their effects on atomic stability.
  • Investigate the formation and properties of deuterium in different environments.
USEFUL FOR

Students and professionals in nuclear physics, researchers studying atomic interactions, and anyone interested in the fundamental forces governing particle physics.

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
