Neutrino detector - Wikipedia
WEBNeutrino detector. A neutrino detector is a physics apparatus which is designed to study neutrinos. Because neutrinos only weakly interact with other particles of matter, neutrino detectors must be very large to detect a significant number of neutrinos. Neutrino detectors are often built underground, to isolate the detector from cosmic rays and ...
Neutrin - Wikipedia
WEBNeutrin. Neutrinul (denumit și neutrino [n 1]) este o particulă elementară neutră cu spinul 1/2, extrem de ușoară, totuși cu masa mai mare decât 0, care participă doar în procesele intermediate de interacțiunile slabe și gravitaționale. Neutrinul este un lepton. Simbolul său este litera greacă (niu).
Neutron - Wikipedia
WEBNeutron. Neutronul este o particulă subatomică, fără nicio sarcină electrică și masă (m n =1,675·10 −27 kg) puțin mai mare decât cea a protonului. Protonii și neutronii constituie nucleele atomilor. Numărul neutronilor, N, al unui atom poate fi diferit pentru nucleele atomice ale aceluiași element. Așa se formează izotopii.
Solar neutrino - Wikipedia
WEBDiagram showing the Sun's components. The core is where nuclear fusion takes place, creating solar neutrinos. A solar neutrino is a neutrino originating from nuclear fusion in the Sun's core, and is the most common type of neutrino passing through any source observed on Earth at any particular moment. [citation needed] Neutrinos are elementary particles …
Neutrino - Wikipedia, den frie encyklopædi
WEBNeutrino. Neutrino. Den første observation af en neutrino fandt sted den 13. november 1970 i et hydrogen-boblekammer på dette historiske fotografi. Den usynlige neutrino rammer en proton, og danner derved tre spor af partikler (t.h.). Neutrinoen omdannes til en myon, det lange spor i fotografiets centrum.
Sterile neutrino - Wikipedia
WEBSterile neutrino. Sterile neutrinos (or inert neutrinos) are hypothetical particles (neutral leptons – neutrinos) that interact only via gravity and not via any of the other fundamental interactions of the Standard Model. [1] The term sterile neutrino is used to distinguish them from the known, ordinary active neutrinos in the Standard Model ...
Neutrino – Wikipedia
WEBNeutriner förekommer till exempel i neutrinostrålningen från kärnreaktionerna i solen och i kosmisk strålning. De skapas också i vanligt betasönderfall, där en neutron sönderfaller till en proton, en elektron och en antielektronneutrino. Energin hos dessa neutriner varierar från källor som bakgrundsstrålningens på 100 μeV, solens ...
Electron neutrino - Wikipedia
WEBThe electron neutrino ( ν e) is an elementary particle which has zero electric charge and a spin of 1 ⁄ 2.Together with the electron, it forms the first generation of leptons, hence the name electron neutrino.It was first hypothesized by Wolfgang Pauli in 1930, to account for missing momentum and missing energy in beta decay, and was discovered in 1956 by a …

Discovery of the neutron - Wikipedia
WEBThe discoveries of the neutron and positron in 1932 were the start of the discoveries of many new particles. Muons were discovered in 1936. Pions and kaons were discovered in 1947, while lambda particles were discovered in 1950. Throughout the 1950s and 1960s, a large number of particles called hadrons were discovered.
