Abstract

This is a second part of a survey for stable isotopes in the mass range 90 < A < 210, to find candidates showing the bound dineutron nuclear reaction output channel after irradiation with neutrons or photons. To this end, the neutron capture reaction cross sections were calculated in the (0 - 30) MeV energy range with the TALYS-2.0 code for nuclei in the outgoing channel, which are expected to host bound dineutrons. This study was performed to find appropriate candidates to observe bound dineutron decay meeting the criteria based on the (n, γ) resonance cross section analysis. This study opens up a new direction in dineutron research with the (n, ${}^{2}n$ +n) and (γ, ${}^{2}n$ ) nuclear reactions.

观测束缚二中子的候选核。第二部分：（n,2n + n）和（γ,2n）核反应

这是对质量范围为 90 < A < 210 的稳定同位素进行调查的第二部分，目的是寻找在中子或光子辐照后显示束缚二中子核反应输出通道的候选物质。为此，利用 TALYS-2.0 代码在（0 - 30）MeV 能量范围内计算了处于输出通道的原子核的中子俘获反应截面，预计这些原子核将承载束缚正中子。这项研究的目的是根据（n，γ）共振截面分析，寻找符合标准的合适候选者来观测束缚正中子衰变。这项研究为（n，n2+n）和（γ，n2）核反应的二中子研究开辟了一个新方向。
