Number 135 (Story #2), July 1, 1993 by Phillip F. Schewe and Ben Stein NEUTRINO MASS AND SOLAR NEUTRINO UPDATE . At the Moriond neutrino meeting held in February in Switzerland, the latest neutrino mass limits reported were 8 eV for the mass of the electron antineutrino (a Livermore result) and 7.2 eV for electron neutrinos (Mainz). Both limits were established in tritium beta decay experiments. As for the solar neutrino problem, a combination of results from the two gallium detector groups, SAGE (former Soviet Union) and GALLEX (Italy), gives a measured flux value of 72 solar neutrino units (one SNU equals 10**-36 neutrino captures per second per detector target atom). This is still low compared to the standard solar model prediction of 125-132 SNU. (CERN Courier, June 1993.)
