The process of neutrino interaction with $${}^{98}\mathrm{Mo}$$ and $${}^{100}\mathrm{Mo}$$ 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 $${}^{98}$$Mo and $${}^{100}$$Mo, $$\sigma(E_{\nu})$$, are presented. Use is made of both experimental
data obtained for the strength functions $$S(E)$$ in ($$p,n$$) and ($${}^{3}$$He, $$t$$) 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 $$\sigma(E_{\nu})$$ 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 $${}^{100}$$Mo
nuclei is estimated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
