Abstract

Objective physical criteria of data reliability allowed us to analyze the cross sections of photoneutron partial reactions (γ, 1n) and (γ, 2n) on ⁵²Cr and ⁹⁰Zr nuclei obtained on bremsstrahlung γ-radiation beams by introducing corrections calculated on the base of statistical theory to the neutron yield cross section σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n). The reasons why the experimental data for the ⁹⁰Zr nucleus fully satisfy the physical criteria, while there are serious doubts in reliability of data for ⁵²Cr nucleus, are discussed.

轫致辐射束实验中轻核和中重核的光子中子反应截面

根据数据可靠性的客观物理标准，通过引入基于统计理论计算的中子产额截面σ(γ, xn) = σ(γ, 1n) + 2σ(γ, 2n)的修正，可以分析轫致辐照γ射线束上52Cr和90Zr核上的光子中子部分反应（γ, 1n）和（γ, 2n）的截面。讨论了90Zr核的实验数据完全满足物理标准，而52Cr核的数据可靠性存在严重质疑的原因。
