The Homestake experiment (sometimes referred to as the Davis experiment or Solar Neutrino Experiment and in original literature called Brookhaven Solar Neutrino Experiment or Brookhaven 37 Cl (Chlorine) Experiment) [1] was an experiment headed by astrophysicists Raymond Davis, Jr. and John N. Bahcall in the late 1960s.
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 with extremely small rest mass and a neutral electric charge .
Detailed observations of the neutrino spectrum from more advanced neutrino observatories produced results which no adjustment of the solar model could accommodate: while the overall lower neutrino flux (which the Homestake experiment results found) required a reduction in the solar core temperature, details in the energy spectrum of the ...
Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
Raymond Davis Jr. (October 14, 1914 – May 31, 2006) was an American chemist and physicist.He is best known as the leader of the Homestake experiment in the 1960s-1980s, which was the first experiment to detect neutrinos emitted from the Sun; for this he shared the 2002 Nobel Prize in Physics.
Solar neutrino experiments combined with KamLAND have measured the so-called solar parameters Δm 2 sol and sin 2 θ sol. Atmospheric neutrino experiments such as Super-Kamiokande together with the K2K and MINOS long baseline accelerator neutrino experiment have determined the so-called atmospheric parameters Δm 2 atm and sin 2 θ atm.
And a U.S.-backed program called the Deep Underground Neutrino Experiment, or DUNE, calls for a particle accelerator to send a beam of neutrinos underground from Illinois to South Dakota starting ...
This resolved the solar neutrino problem: the electron neutrinos produced in the Sun had partly changed into other flavors which the experiments could not detect. Although individual experiments, such as the set of solar neutrino experiments, are consistent with non-oscillatory mechanisms of neutrino flavor conversion, taken altogether ...
