| contents | The Borexino Collaboration interprets its data within the framework of Bulk Silicate Earth model and the model of the Sun with high metallicity. Other authors have given a different interpretation of the same data within the framework of Hydridic Earth model and low-metallicity Sun model. In order to understand what occasion takes place in Nature, the Borexino single events energy spectrum was numerically simulated using the Monte Carlo method for various assumptions about the processes that could exist in Nature. The existence of large potassium geo-antineutrino flux and its absence were considered. At the same time, the high or low metallicity of the Sun were included in simulations. A comparison of counting rates reconstruction from simulated data with the reconstruction ones from Borexino single events spectrum demonstrates that large potassium geo-antineutrino flux with low metallicity of the Sun is preferable and is realized in Nature. |
