Sensitivity of the Solar-Neutrino Fluxes *

The sensitivity of the solar-neutrino fluxes to localized changes in the opacity and the equation of state is calculated. The sensitivity to changes in the equation of state reaches a maximum near 8 × 10^e°K and is in general much larger than the sensitivity to opacity changes. The effect of various parameters on the predicted rate of neutrino capture in the ³⁷Cl experiment is summarized in equation (8). The characteristic numerical properties of a standard solar model are then presented. Several general conclusions are justified on the basis of the variations considered. In particular, an assessment is given of the relation between the theory of solar models and the experimental results of Davis, Harmer, and Hoffman.
