Neutrinos are elementary particles, whose existence was predicted in 1930 by Pauli. It was clear to him that apply to core processes the law of conservation of energy also has that something was missing and that this added to the particle “neutrino” could be solved.
It is now fully accepted that the neutrino is a tiny particle with no charge and with very low mass. Neutrinos are released in nuclear fusion processes, as they proceed in stars in supernova explosions, or in the particle accelerators of particle physicists. Neutrinos have little interaction with other matter. Every second, billions of neutrinos fly through our bodies without us noticing something like this. The neutrino is a “nothing”. But still ..
Detect neutrinos is due to the low interaction with other matter very difficult. Raymond Davis has discussed for 40 years, with the possible techniques of their evidence and, despite great skepticism of his colleagues, continued the search. The first evidence came in the 50s in a reactor (Brookhaven’s Graphite Research Kernreactor). Later, the detection of released in the solar neutrinos in a detector was in the “Homestake mine in South Dakota (USA), and so have the stamina and inventiveness of Davis rewarded. Continue reading →
