What Fraction of Potassium in the Earth Does the Borexino Experiment Allow?

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The authors consider results from analyzing the energy spectrum of single events obtained in Phase III of the Borexino experiment. The experimental spectrum is fitted by a set of standard sources of single events with the addition of events from potassium geo-antineutrino (40K-geo-ν) scattering on electrons. The adding of 40K-geo-ν events improves the agreement between the experimental and fitted spectra. Experimental results indicate considerable amounts of potassium in the Earth.
