Abstract
The charge-exchange strength functions \(S(E)\) for the isotopes \({}^{98,100}\)Mo are presented. Both experimental data obtained for the strength functions \(S(E)\) in (\(p,n\)) and (\({}^{3}\)He, \(t\)) reactions and the strength functions \(S(E)\) calculated within the self-consistent theory of finite Fermi systems are analyzed. The resonance structure of the strength function \(S(E)\) is investigated, and the Gamow–Teller, analog, and pygmy resonances are isolated. The quenching effect manifesting itself as a sum-rule shortfall, which changes the normalization of the strength function \(S(E)\), is studied. It is indicated that the resonance structure of the strength function \(S(E)\) is of decisive importance for the calculation and analysis of neutrino capture by nuclei.
