摘要

利用活化法测定硒同位素 74Se 的（n，γ）横截面的研究具有潜在的应用价值，可能会引起您的兴趣。辐照由电子医用加速器产生的轫致辐射光子束进行，产生的中子能谱范围为 1 keV 至 1 MeV。75Se 核的产生是通过医用直线加速器场内的中子俘获和光子核反应相结合的方式进行的。光子和中子诱导的贡献都必须加以研究。使用 TALYS 2.0 核反应代码计算了 74Se 的光子和中子俘获截面，并与我们的测量结果进行了比较。结果表明，这种方法可用于研究医疗中心的核天体物理学相关反应，为研究和应用开辟了新途径。

Neutron capture cross-section of p-nucleus 74Se in the keV region using the activation method

The research on the (n, γ) cross section of selenium isotope ⁷⁴Se, determined using the activation method, has potential applications that could pique your interest. The irradiation was conducted by a Bremsstrahlung photon beam generated by an electron medical accelerator, yielding neutrons within an energy spectrum ranging from 1 keV to 1 MeV. The production of ⁷⁵Se nuclei occurs through a combination of neutron capture and photonuclear reactions in the field of a medical linear accelerator. Both the photon- and neutron-induced contributions had to be studied. Photo- and neutron-capture cross sections of ⁷⁴Se were calculated using the TALYS 2.0 nuclear reaction code and compared with our measurement. The results show that this method could be employed to study reactions relevant to nuclear astrophysics in medical centers, opening up new avenues for research and application.
