Abstract

This work deals with the possible solution of the solar neutrino problem in the framework of the resonant neutrino spin-flavor precession scenario. The event rate results from the solar neutrino experiments as well as the recoil electron energy spectrum from SuperKamiokande are used to constrain the free parameters of the neutrino in this model. We consider two kinds of magnetic profiles inside the sun. For both cases, a static and a twisting field are discussed.
