Query: A new neutrino source for the study of the solar neutrino physics in the
  vacuum-matter transition region   Production of a neutrino source through proton induced reaction is studied by
using the particle transport code, GEANT4. Unstable isotope such as $^{27}$Si
can be produced when $^{27}$Al target is bombarded by 15 MeV energetic proton
beams. Through the beta decay process of the unstable isotope, a new
electron-neutrino source in the 1.0 $\sim$ 5.0 MeV energy range is obtained.
Proton induced reactions are simulated with JENDL High Energy File 2007
(JENDL/HE-2007) data and other nuclear data. For radioactive decay processes,
we use "G4RadioactiveDecay" model based on the Evaluated Nuclear Structure Data
File (ENSDF). We suggest target systems required for future's solar neutrino
experiments, in particular, for the vacuum-matter transition region. As for the
detection system of the new neutrino source, we evaluate reaction rates for
available radiochemical detectors and LENA type scintillator detector.
Possibility of detecting sterile neutrinos is also discussed.
