Abstract
A possible particle-physics solution is proposed to the recently reported discrepancy between the Homestake and Kamiokande II experiments concerning the ‘‘time variation’’ of the solar-neutrino flux. It is pointed out that some of the models giving rise to a large magnetic moment of electron neutrinos include the possibility that the right-handed neutrino interacts with electrons strongly enough so that Kamiokande does not see the time variation, while the Homestake experiment shows the time variation in anticorrelation with solar activity due to the neutrino helicity flip in the sun.
