Abstract

Calculations are presented for cross section σ(E_ν) of solar neutrino capture by ⁷¹Ga nuclei. The calculations are based on experimental data on force function S(E) obtained in charge-exchange reactions ⁷¹Ga(p, n)⁷¹Ge and ⁷¹Ga(³He, t)⁷¹Ge. Charge-exchange force function S(E) for ⁷¹Ga is calculated using the self-consistent theory of finite Fermi systems. The effect the resonance structure of S(E) has on calculated cross section σ(E_ν) is studied. It is shown that the resonance part adds about 5% to the rate of the reaction estimated with only discrete states.

核共振以及中微子与Ga-Ge系统之间的相互作用

摘要

计算是为了截面σ（Ë _ν）由太阳中微子捕获的⁷¹嘎核。该计算基于电荷交换反应⁷¹ Ga（p，n）⁷¹ Ge和⁷¹ Ga（³ He，t）⁷¹ Ge中获得的力函数S（E）的实验数据。使用有限费米系统的自洽理论计算了⁷¹ Ga的电荷交换力函数S（E）。影响S（E的共振结构。）已计算出的横截面σ（Ë _ν）进行了研究。结果表明，共振部分仅在离散状态下估计的反应速率增加了约5％。
