Abstract
We derive a lower limit on the Beryllium neutrino flux on earth, Phi(Be)(min) = 1 . 10(9) cm(-2) s(-1), in the absence of oscillations, by using helioseismic data, the B-neutrino flux; measured by Superkamiokande and the hydrogen abundance at the solar center predicted by Standard Solar Model (SSM) calculations. We emphasize that this abundance is the only result of SSMs needed for getting Phi(Be)(min). We also derive lower bounds for the Gallium signal, G(min) = (91 +/- 3) SNU, and for the Chlorine signal, C(min) = (3.24 +/- 0.14) SNU, which are about 3 sigma above their corresponding experimental values, G(exp) = (72 +/- 6) SNU and C(exp) = (2.56 +/- 0.22) SNU.
