Abstract
A new scheme for the short baseline electron antineutrino () disappearance study is investigated. We propose to use an intense neutron emitter, 252Cf, which produces a 8Li isotope through the 7Li(n,γ)8Li reaction; 8Li is a emitter via decay. Because this source needs neither accelerator nor reactor facilities, the can be placed on any neutrino detector as closely as possible. This short baseline circumstance with a suitable detector enables us to study the existence of possible sterile neutrinos, in particular, on 1 eV mass scale. Also, complementary comparison studies among different neutrino detectors can become feasible by using from the 8Li source. As an example, applications to hemisphere and cylinder shape scintillator detectors are performed in detail with the expectation signal modification by the sterile neutrino. Sensitivities to mass and mixing angles of sterile neutrinos are also presented for comparison with those of other neutrino experiments.
