11 C är en radioisotop vars kärna består av 6 protoner och 5 neutroner.Den sönderfaller till 11 B.Detta sönderfall sker främst på grund av positronemission; emellertid är det cirka 0,19–0,23 % av fallet ett resultat av elektroninfångning.

Elektroner kan skapas i atomkärnan av den svaga kraften. En neutron i kärnan förvandlas till en proton och en elektron plus en neutrino. Elektronen är opåverkad

U fizici, neutron je subatomska čestica, simbol n ili n 0, bez naelektrisanja i sa masom od 940 MeV/c 2 (1.6749 h 10-27 kg, malo većom od mase protona).Njegov spin je 1/2. . Neutron je sastavni deo jezgra svakog atoma osim najrasprostranjenijeg izotopa vodonika, čije se jezgro sastoji samo od jednog pr Neutron Die kwarksamestelling van ’n neutron: een opkwark (u) en twee afkwarke (d). Die kleure van die individuele kwarke is arbitrêr, maar al drie kleure moet teenwoordig wees. When two neutron stars orbit each other closely, they spiral inward as time passes due to gravitational radiation.When the two neutron stars meet, their merger leads to the formation of either a more massive neutron star, or a black hole (depending on whether the mass of the remnant exceeds the Tolman–Oppenheimer–Volkoff limit).

Az atommagban a protonok és neutronok (közös nevük: nukleonok - magalkotók) közötti kölcsönhatás a magerő, mely a kvarkok közötti erős kölcsönhatás gyengébb maradványa.

A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. The neutron release generated by a nuclear fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by

The term is mainly used in astrophysics to refer to dense stellar objects where gravitational pressure is so extreme that 2003-03-29 A neutron star is a very small and dense star made almost completely of neutrons.They are small stars with a radius of about 11–11.5 kilometres.They have a mass of about twice that of the Sun.They are the smallest and densest stars known to exist in the Universe. They are what is left of a huge star which exploded as a supernova.. The density of the star is like that of the nucleus of an atom.

Neutrons bind with protons with the residual strong force. The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol μ n. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments. The neutron interacts with normal matter through either the nuclear force or its magnetic moment. When two neutron stars orbit each other closely, they spiral inward as time passes due to gravitational radiation.When the two neutron stars meet, their merger leads to the formation of either a more massive neutron star, or a black hole (depending on whether the mass of the remnant exceeds the Tolman–Oppenheimer–Volkoff limit).The merger can also create a magnetic field that is trillions Neutron reflectometry is a neutron diffraction technique for measuring the structure of thin films, similar to the often complementary techniques of X-ray reflectivity and ellipsometry.The technique provides valuable information over a wide variety of scientific and technological applications including chemical aggregation, polymer and surfactant adsorption, structure of thin film magnetic Neutron is a fictional comic book supervillain in the DC Universe, appearing usually as an adversary of Superman.

jag tittade på wikipedia men hittar inte hur många neutroner koppar har förstår inte hur man ska hitta svaret på det. neutroner, radioaktiv strålning och frigör energi. • Reaktionen kan starta spontant eller genom inskjutning av neutroner, även kallad neutroninducerad fission.

This term is very rarely used in scientific literature, for three reasons: there are multiple definitions for the term "neutronium"; there is considerable Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states. A neuron or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the main component of nervous tissue in all animals except sponges and placozoa.

In fisika is die neutron 'n subatomiese deeltjie met geen netto elektriese lading nie en 'n massa van 939,573 eV/ c2, wat dit effens swaarder as 'n proton maak. Sy spin is ½. Sy antideeltjie word die antineutron genoem. Die neutron en proton is albei voorbeelde van 'n nukleon.

In some cases, a smaller facility will provide high energy neutrons (e.g. 2.5 MeV or 14 MeV fusion neutrons) using existing neutron generator technologies.
