Abstract

The interaction of solar neutrinos with the ¹²⁸Te and ¹³⁰Te isotopes was studied taking into account the resonance structure of charge-exchange strength functions S(E). An analysis was made of both experimental data on the strength functions S(E) obtained in the reactions (³He, t) and the strength functions S(E) calculated in the microscopic theory of finite Fermi systems. The resonance structure of the S(E) strength function was investigated, and the Gamow–Teller, analog, and pygmy resonances were identified. The capture cross sections σ(E) of solar neutrinos by the two isotopes were calculated with consideration of the resonance structure of the strength function S(E), and the influence of the resonances on the energy dependence σ(E) was analyzed. It was shown that, when calculating the cross section σ(E), the resonance structure of the strength function S(E) should be taken into account.

太阳中微子与 128Te 和 130Te 的相互作用

摘要研究了太阳中微子与 128Te 和 130Te 同位素的相互作用，同时考虑了电荷交换强度函数 S(E) 的共振结构。研究分析了在反应（3He, t）中获得的强度函数S(E)的实验数据和有限费米系统微观理论计算的强度函数S(E)。研究了 S(E) 强度函数的共振结构，确定了伽莫-泰勒共振、模拟共振和侏儒共振。考虑到 S(E) 强度函数的共振结构，计算了两种同位素对太阳中微子的俘获截面 σ(E)，并分析了共振对能量依赖性 σ(E)的影响。结果表明，在计算横截面 σ(E) 时，应考虑强度函数 S(E) 的共振结构。
