Resumo
The results of analysis for the single events energy spectrum obtained in phase III of Borexino detector operation are considered. The experimental spectrum was fitted by a set of standard single events sources with the addition of events from potassium geo-antineutrinos (40K-geo-v) scattering on electrons. The addition of 40K-geo-v events makes it possible to improve the agreement of the experimental and fitted spectra. Experimental results indicate the presence of a significant amount of potassium in the Earth.
