Discussion of the oscillating geoantineutrino deficit problem

Abstract

The estimations of integral intensity and energy spectrum of geoantineutrino on the Earth's surface (in the absence of oscillations) from different radioactive sources (U, Th and K) are obtained on the basis of temporal evolution analysis of radiogenic heat-evolution power of the Earth w4thin the framework of model of geochemical processes of mantle differentiation and earth's crust growth.
