Analyzing the uncertainty of antineutrino spectrum of georeactor origin, we show that the theoretical (which takes into account the soliton-like nuclear georeactor) total reactor antineutrino spectra describe with good accuracy the experimental KamLAND-data over the years of 2002-2007 and 2002-2009, respectively. At the same time, the parameters of mixing (△m221=2.5×10-5 eV2, tan2θ12=0.437) calculated within the framework of georeactor hypothesis substantially differ from the parameters of mixing ((△m221=7.49×10-5 eV2, tan2θ12=0.436) obtained in KamLAND-experiment for total exposure over the period of 2002-2009. By triangulation of KamLAND and Borexino data we have constructed the coordinate location of soliton-like nuclear georeactors on the boundary of the liquid and solid phases of the Earth core.展开更多
