Solar neutrino capture by 128, 130Te isotopes and Baksan Large Neutrino Telescope Project

Abstract

This paper discusses the charge-exchange strength functions $S(E)$ of the isotopes ${}^{128,130}$Te. The experimental data of the $S(E)$ strength functions obtained from ${(}^3\mathrm{He},t)$ reactions, as well as the $S(E)$ strength functions calculated in the microscopic theory of finite fermi-systems, are analyzed. The resonance structure of the strength function $S(E)$ is examined, and the Gamow-Teller and Pygmy resonances are identified. The resonance structure of the strength function $S(E)$ is vital for the calculation and analysis of the process of neutrino capture by atomic nuclei.
