The present and past neutrino luminosity of the sun
Abstract
The neutrino radiation from the sun can give direct information on the basic nuclear fusion processes that provide the solar energy. Results are reported which have been obtained over the last seven years with the Brookhaven solar neutrino detector that depends upon the neutrino capture reaction, Cl-37(nu,e(-))Ar-37. These results do not agree with the predictions of the standard solar model. It is of great interest to know whether the lack of agreement between the measurements and theoretical expectation could possibly be explained by a secular variation in the rate of the fusion process. Two radiochemical neutrino detection techniques have been proposed previously that could in principle record the neutrino flux of the past. An analysis is given of the expected background processes for these experiments. These and other possible methods of recording the past solar neutrino luminosity are discussed in relation to variations expected from theoretical solar models.
