Query: Cross sections of solar neutrino capture by 127I nuclei and Gamow Teller
  resonances   Solar neutrino capture cross-section by 127I nucleus has been studied with
taking into account the influence of the resonance structure of the nuclear
strength function S(E). Three types of isobaric resonances: giant Gamow-Teller,
analog resonance and low-lying Gamow-Teller pigmy resonances has been
investigated on the framework of self-consistent theory of finite Fermi
systems. The calculations have been performed considering the resonance
structure of the charge-exchange strength function S(E). We analyze the effect
of each resonance on the energy dependence of the cross-section. It has been
shown that all high-lying resonances should be considered. Neutron emission
process for high energy nuclear excitation leads to formation 126Xe isotope. We
evaluate contribution from various sources of solar neutrinos to the
126Xe/127Xe isotopes ratio formed by energetic neutrinos. 126Xe/127Xe isotope
ratio could be an indicator of high-energy boron neutrinos in the solar
spectrum. We also discuss the uncertainties in the often used Fermi-functions
calculations.
