AI总结:

考虑电荷交换共振效应,利用实验与理论强度函数研究了太阳中微子与$^{98,100}$Mo同位素的相互作用,计算了各共振及中微子谱分量的俘获截面贡献,并评估了其作为双β衰变背景的影响。

摘要:

考虑电荷交换共振效应,研究了中微子与$^{98}$Mo和$^{100}$Mo同位素的相互作用过程。使用了电荷交换反应$(p; n)$和$(^3\mathrm{He}, t)$的强度函数$S(E)$实验数据,以及基于有限费米系统理论计算的强度函数$S(E)$。研究了$S(E)$的共振结构对太阳中微子截面的影响。考察了每个高位共振对俘获截面$σ(E_ν)$的贡献。计算了太阳中微子谱所有分量的贡献。估计了太阳中微子不同分量作为$^{100}$Mo双β衰变实验背景的贡献。

英文摘要:

The process of neutrino interaction with $^{98}$Mo and $^{100}$Mo isotopes is studied taking into consideration the effect of charge-exchange resonances. The experimental data on the strength functions $S(E)$ obtained in charge-exchange reactions $(p; n)$ and $(^3\mathrm{He}, t)$ and the strength functions $S(E)$ calculated within the theory of finite Fermi systems were used. We studied the effect of the resonance structure of $S(E)$ on the cross sections for solar-neutrino. We investigated the contribution of each high-lying resonance to the capture cross section $σ(E_ν)$. The contributions of all components of the solar neutrino spectrum are calculated. We estimate the contribution of different components of solar neutrinos as the background for the double-beta decay experiments on $^{100}$Mo.
