Query: Antineutrino Spectrum of the Earth and the Problem of Oscillating
  Geoantineutrino Deficit   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.
