Neutron probe — (e=neutron emitter d=detector b=shielding c=counter). A neutron probe is a device used to measure the quantity of water present in soil. A typical neutron probe contains a pellet of americium 241 and beryllium. The alpha particles emitted by the… … Wikipedia
Neutron detection — is the effective detection of neutrons entering a well positioned detector. There are two key aspects to effective neutron detection: hardware and software. Detection hardware refers to the kind of neutron detector used (the most common today is… … Wikipedia
Neutron — This article is about the subatomic particle. For other uses, see Neutron (disambiguation). Neutron The quark structure of the neutron. (The color assignment of individual quarks is not important, only that all three colors are present.)… … Wikipedia
Neutron moisture gauge — A neutron moisture meter is a moisture meter utilizing neutron scattering. The meters are most frequently used to measure the water content in soil or rock. The technique is non destructive, and is sensitive to moisture in the bulk of the target… … Wikipedia
Neutron star — redirects here. For the story by Larry Niven, see Neutron Star (short story). Neutron stars crush half a million times more mass than Earth into a sphere no larger than Manhattan. A neutron star is a type of stellar remnant that can result from… … Wikipedia
Neutron — Représentation schématique de la composition en quarks d un neutron, avec deux quarks d et un quark u. L interaction forte est transmise par des gluons (représentés ici par un tracé sinusoïdal). La couleur des quarks fait référence aux trois… … Wikipédia en Français
Neutron spectroscopy — Neutron scattering is a spectroscopic method that uses neutron scattering to measure atomic and magnetic motions of atoms. Inelastic neutron scattering observes the change in the energy of the neutron as it scatters from a sample and can be used… … Wikipedia
Neutron-star oscillations — Asteroseismology studies the internal structure of our Sun and other stars using oscillations. These can be studied by interpreting the temporal frequency spectrum acquired through observations [cite journal|… … Wikipedia
Neutron-star oscillation — Asteroseismology studies the internal structure of our Sun and other stars using oscillations. These can be studied by interpreting the temporal frequency spectrum acquired through observations[1]. In the same way, the more extreme neutron stars… … Wikipedia
