“for their pioneering observations of astronomical phenomena by detection of neutrinos, thus creating the emerging field of neutrino astronomy.”
The observations of the elusive neutrinos of astrophysical origin, by Davis and by Koshiba, have opened a new window of opportunity for the study of astronomical objects, such as the sun and exploding stars, and the study of fundamental properties of matter. Davis and Koshiba developed complementary methods that have yielded important scientific results and have inspired the development of new neutrino detection experiments.
Professor Raymond Davis Jr. developed, through persistent and sustained efforts, the first large-scale radiochemical neutrino detectors and obtained the first measurement of the flux of neutrinos from the sun. Davis developed the techniques of extracting from a large detector volume, the few atoms of argon produced by incoming neutrinos. With the continuing theoretical support of John Bahcall, these measurements were shown to provide a very stringent test for theories of the solar interior.
