Byron K. Jennings TRIUMF One of the outstanding problems in physics today is with the observed number of solar neutrinos -- significantly fewer are observed than predicted. The high energy neutrinos to which some neutrino detectors, including SNO, are sensitive are produced by the decay of Boron 8 in the sun. In this talk I discuss the solar neutrino problem with emphasis on the astrophysical S factor for Boron 8 production. The previously unexplained low energy behaviour of the S factor will be clarified and the uncertainties it introduces in the predicted number of neutrinos discussed. The solar neutrino problem can NOT be solved by this bit of nuclear physics.
