Number 14 (Story #1), December 27, 1990 by Phillip F. Schewe and Ben Stein THE SOLAR NEUTRINO FLUX shows no day/night or semiannual variations, a conclusion based on 1040 days of monitoring neutrinos from Boron-8 decays in the sun. This finding, recorded at the Kamiokande-II detector in Japan puts limits on the amount by which neutrinos can oscillate from one type to another, a phenomenon suggested to explain the apparent deficit of solar neutrinos measured on Earth.
