WHAT CAN 4 SOLAR-NEUTRINO EXPERIMENTS TELL US ABOUT THE MAGNETIC-MOMENT SOLUTION TO THE SOLAR-NEUTRINO PROBLEM

The results reported by the four solar neutrino experiments (Homestake , Kamiokande, SAGE, Gallex) are analyzed from the point of view of the magnetic moment solution to the solar neutrino problem. The neutrino deficit reported by the gallium experiments (SAGE, Gallex) is apparent ly not as large as the one reported by Homestake and Kamiokande, a phe nomenon suggesting a greater suppression in the large energy solar neu trino sector but also consistent with a uniform suppression for all ne utrinos. Both uniform and nonuniform suppressions are examined for thr ee different variants of the solar magnetic field and the possible par ameter ranges for DELTA2m21 and mu(nu) are investigated. Massless neut rinos are not excluded and in all cases DELTA2m21 < 10(-5) eV2. The an ticorrelation of the neutrino flux with sunspot activity is possible a ny of the experiments but is in no way implied by a sizable magnetic m oment and magnetic field.
