Description
To investigate the existence of sterile neutrino, we propose a new neutrinoproduction method using 13C beams and a 9Be target for short-baseline electron anti-neutrino disappearance study. The production of secondary unstable isotopes which can emit neutrinos from the 13C + 9Be reaction is calculated with three different nucleus-nucleus (AA) reaction models. Isotope yields are obtained using these models, but the results of the electron anti-neutrino are found to have unanimous similarities. This feature gives anopportunity to study neutrino oscillation through shape analysis. In this work, expected electron anti-neutrino and event rates are discussed in detail through intensive simulation of the light ion collision reaction and the neutrino from the beta decay of unstable isotopes followed by this collision. Together with the reactor and accelerator anomalies, the present proposed source is shown to be a practically alternative test of the existence of sterile neutrino.
