  We have found allowed squared mass difference, magnetic field, mixing angle -
regions for the Resonant Spin-Flavor Precession Solution to the Solar Neutrino
Problem fitted with the data of all acting solar neutrino experiments. The
typical mass difference region varying in dependence on the mixing angle is
allowed for some discrete magnetic field regions in a wide range for the fixed
neutrino transition magnetic moment. Except of the first allowed range with the
lowest field strength the magnetic field amplitude within other discrete
allowed regions depend essentially on the shape of a regular magnetic field
profile in the convective zone of the Sun. For the non-zero neutrino mixing one
can find at 99.9% C.L. an upper limit on the mixing, originated by the
non-observation of electron antineutrinos in the SuperKamiokande detector. This
limit occurs also sensitive to the magnetic field profile. While at 67% C.L.
there is another more stringent upper limit coming from inconsistency of the
gallium experiments with others. A new allowed region appears in the case of an
additional assumption that the Homestake data are 1.3 times less than the
experimental event rate.
