  In this paper we show that the neutrino observables, including an information
about the transverse neutrino spin polarization, can be sensitive to the
effects coming from the interference terms between the standard vector V, axial
A couplings of L-handed neutrinos and exotic scalar S coupling of R-handed ones
in the differential cross section. Our analysis is based on the electron
neutrino-electron elastic scattering. This reaction is considered at the level
of the four-fermion point interaction. Neutrinos are assumed to be massive and
to be polarized Dirac fermions coming from the Sun.
