Resonant Spin-Flavor Precession of Neutrinos As a Possible Solution to   the Solar Neutrino Problem
  Recent developments of the resonant neutrino spin-flavor precession scenario and its applications to the solar neutrino problem are reviewed. We discuss in particular the possibilities of reconciliation of strong time variations of the solar neutrino flux observed in the Homestake ${}^{37}\$Cl experiment with little or no time variation seen in the Kamiokande II experiment.
