The 8^8B Neutrino Spectrum

Knowledge of the energy spectrum of $^8$B neutrinos is an important ingredient for interpreting experiments that detect energetic neutrinos from the Sun. The neutrino spectrum deviates from the allowed approximation because of the broad alpha-unstable $^8$Be final state and recoil order corrections to the beta decay. We have measured the total energy of the alpha particles emitted following the beta decay of $^8$B. The measured spectrum is inconsistent with some previous measurements, in particular with a recent experiment of comparable precision. The beta decay strength function for the transition from $^8$B to the accessible excitation energies in $^8$Be is fit to the alpha energy spectrum using the R-matrix approach. Both the positron and neutrino energy spectra, corrected for recoil order effects, are constructed from the strength function. The positron spectrum is in good agreement with a previous direct measurement. The neutrino spectrum disagrees with previous experiments, particularly for neutrino energies above 12 MeV.Comment: 15 pages, 13 figures, 4 tables, submitted to Phys. Rev. C, typos correcte

Neutrino oscillations in vortex and twisting magnetic fields

The behavior of the neutrino flux in vortex and twisting magnetic fields is considered within the left-right symmetric model. By way of illustration of the magnetic fields we discuss the magnetic fields of the coupled sunspots (CS's) which are the sources of the future solar flares. It is expected that the neutrinos have such multipole moments as the charge radius, the magnetic and anapole moments. The evolution equation in the Schrodinger-like form is found and all magnetic-induced resonance conversions are analyzed. It is demonstrated that in the case of the super flares one may detect the depletion of the $\nu_{eL}$ neutrinos caused by their resonance absorptions when they travel through the CS magnetic fields. Observations of this phenomena could be carried out at neutrino telescopes of the next generation whose work is based on the reaction of the coherent elastic neutrino-nucleus scattering.Comment: 25 page
