Abstract: | A discussion is given on the prospects for making a precise determination of the value of sin2θ W (θW is the Weinberg angle) and for improving the sensitivity of the search for the antineutrino magnetic moment to ≈1.5×10−11μB and for the
mixing parameter to sin22θ ≈10−2 by measuring in a single experiment the cross sections for
scattering for the reaction
. Such an experiment with ∼100 000 events/yr detected for each reaction can be carried out, for example, using the BOREXINO
detector and an approximately 10 MCi 90Sr source.
