Monte-Carlo sensitivity study for sterile neutrino search with $^{144}$Ce - $^{144}$Pr source and liquid scintillation detectors of various geometries

Expected energy spectra calculations for large volume liquid scintillation detectors to inverse $beta$-decay for antineutrinos produced by $^{144}$Ce -- $^{144}$Pr artificial source have been performed. The calculations were carried out through Monte-Carlo method within GEANT4.10 framework and were purposed to search for neutrino oscillation to sterile eigenstate with mass about 1 eV. The analysis of relative sensitivity to oscillation parameters for different detector shapes has been performed.
