Test of beta and antineutrino spectra symmetry in beta-decay

Abstract

The mechanism of beta decay in nature is not understood yet. Mirrored energy spectra of electron and antineutrino can clarify the situation. A special experiment is needed to measure antineutrino spectrum from known beta-decaying isotope to compare it with the beta one. One of ongoing experiments with large volume detector can be chosen to make the experiment. Another possibility is to make a special experiment close to a powerful source of mixture of known beta-decaying isotopes. If sufficient differences in shape will be observed the method of antineutrino spectrum calculation should be revised.
