Interior Structure of the Sun

MUCH has been written about the solar neutrino experiment of R. Davis, jun. 1 . In this experiment, the counting rate expected from boron 8 ( 8 B) solar neutrinos 2 was an order of magnitude greater than the experimental background counting rate—but only the background counting rate was obtained 3 . The purpose of this communication is to state briefly why I think this null result is important, and to give additional evidence that the various models of the solar interior used to predict the neutrino fluxes are significantly different from the structure of the real Sun.
