The 13C (α,n)16O reaction cross-section is important data for nuclear physics, astrophysical, and neutrino physics experiments, however, they exhibit uncertainties due to the discrepancies in the experimental data. In this study, using the Nedis-2m program code, the energy spectrum of α-induced neutrons in a thin carbon target was calculated and the corresponding reaction cross-section was refined in the alpha particle energy range of 5–8 MeV. The results were used to calculate the intensity and energy spectrum of background neutrons produced in the liquid scintillator of KamLAND. The results will be useful in a variety of astrophysical and neutrino experiments especially those based on LS or Gd-LS detectors.

KamLAND液体闪烁体中13C(alpha,n)16O反应的中子产额和能谱:Nedis-2m模拟

13 C(α,n)的16 ö反应横截面是用于核物理学,天体物理学,和中微子物理实验的重要数据,但是,它们表现出的不确定性,由于在实验数据的差异。在这项研究中,使用 Nedis-2m 程序代码,计算了薄碳靶中 α 诱导中子的能谱,并在 5-8 MeV 的 α 粒子能量范围内细化了相应的反应截面。计算结果用于计算 KamLAND 液体闪烁体中产生的背景中子的强度和能谱。结果将用于各种天体物理和中微子实验,尤其是基于 LS 或 Gd-LS 探测器的实验。
