Science reporter magazine for ias
Science reporter magazine for ias Neutrinos theorized by Pauli in 1930 and detected by Clyde Cowan and Frederich Reines in 1956 were actually anti-neutrinos from a nuclear reactor. Hence the existence of anti-neutrinowas confirmed in 1956 itself. Actually anti-neutrinos are produced in negative beta decay that typically occurs in a nuclear reactor. An unstable fission fragment (in a nuclear reactor) with excess of neutrons undergoes negative beta decay when neutron is converted into a proton an electron and an electron anti-neutrino. Therefore each nuclear reactor is a very powerful source of anti neutrinos On the other hand the most powerful source of neutrinos is the Sun. In the fusion reaction taking place in the Sun four hydrogen nuclei combine to form a helium2 nucleus. Neutrinos are generated in the fusion process taking place in the Sun science magazine subscription
