Joint analysis of spectral reactor neutrino experiments
  The analysis of experiments at nuclear reactors where inverse beta decay reaction positron spectrum was measured at different distances from reactor core is presented here. It was found that there appear three enclosed zones of neutrino oscillation parameters when joint analysis is applied on the ${\Delta}m^{2}-\sin^{2}2{\theta}$ plane. The parameters that found are partially crossed with similar regions originating from other non reactor experiments where they observed neutrino oscillations having unusual mass parameter about 1 eV^2 and amplitude about 0.04. Confidence level for observed regions achieves the value of 99.9%.
