![]() Further measurements carried out by SNO have since confirmed and improved the precision of the original result. The total flux of all neutrino flavours measured by SNO agrees well with the theoretical prediction. If neutrinos actually have a tiny amount of mass (the original theory predicted that they were massless), then solar neutrinos can change. This oscillation in turn implies that neutrinos have non-zero masses. that they can transmute into one another), as they travel in the sun. On 18 June 2001, the first scientific results of SNO were published, bringing the first clear evidence that neutrinos oscillate (i.e. The new findings update last years CC and ES data. ![]() Now the definitive result has been tendered by SNO scientists at the Albuquerque meeting. Thus, such detector can measure neutrino oscillations directly. The SNO data, when supplemented with ES data from the Super Kamiokande experiment in Japan, provided preliminary evidence a year ago for the neutrino-oscillation solution for the solar neutrino problem. In 1984, Herb Chen of the University of California at Irvine first pointed out the advantages of using heavy water as a detector for solar neutrinos.Unlike previous detectors, using heavy water would make the detector sensitive to two reactions, one reaction sensitive to all neutrino flavours, the other reaction sensitive to only electron neutrino. All of the solar neutrino detectors prior to SNO had been sensitive primarily or exclusively to electron neutrinos and yielded little to no information on muon neutrinos and tau neutrinos. Yes, and an experiment that led to a Nobel prize was done ![]() ![]() However wouldn't a tau neutrino and muon neutrino be detected as well? ![]()
