Application of Selenium-82 for Short Base Neutrino Oscillations Searches

Characteristics of neutrino absorption by ${}^{82}$Se nucleus reaction – low threshold value, high absorption cross section of neutrinos, emitted by artificial sources, make selenium-82 perspective object to search for new neutrino species in calibration experiments. One of the interesting possibilities is usage of scintillating crystals. In (3+1) model for spherical geometry the expression for neutrino path length in a setup in the presence of oscillations is obtained and the scheme of experiment is proposed.
