Abstract

We examine the calculation of the solar neutrino flux based on the standard solar model (SSM). It is found that the solar neutrino data (KAMIOKANDE experiment) can be well described by the SSM with careful employment of nuclear data of $^7Be (p,��) ^{8} B$. The main point is that the simple-minded product ansatz of Coulomb plus nuclear parts should have a few percent uncertainties which induce the large reduction of the neutrino flux from $^8 B$. Also, if the electron capture of $^7 Be$ inside the sun is suppressed, then the GALLEX experiment can be understood by the SSM calculation.
