摘要：
The process of neutrino interaction with Mo-98 and Mo-100 nuclei is studied with allowance for the effect of charge-exchange resonances. The results obtained by calculating the cross section for solar-neutrino capture by the isotopes Mo-98 and Mo-100, sigma(E-v), are presented. Use is made of both experimental data obtained for the strength functions S(E) in (p, n) and (He-3, t) charge-exchange reactions and the strength functions S(E) calculated within the theory of finite Fermi systems. The effect of the resonance structure of S(E) on the calculated cross sections for solar-neutrino capture is studied, and the contribution of each high-lying resonance to the capture cross section sigma(E-v) is isolated. The contributions of all components of the solar neutrino spectrum are calculated. The contribution of background solar neutrinos to the double-beta decay of Mo-100 nuclei is estimated.
