Abstract:
The experimental data obtained on the liquid scintillation detector LSD are analyzed for the purpose of searching for the solar electron antineutrino flux predicted in the model of spin-flavor precession of the neutrino. The currently most accurate upper limit on the solar v̄e/ve flux ratio is established: Φv̄/Φv⩽1.7% (90% confidence range). Pis’ma Zh. éksp. Teor.
