中子感生放射性:辐射俘获的热力学方法

Radioactivity Induced by Neutrons: a Thermodynamic Approach to Radiative Capture

Alberto De Gregorio

摘要:

当恩里科·费米发现慢中子时,他仅仅提到了中子和质子之间众所周知的散射截面,就解释了慢中子在诱导放射性方面的巨大效率。他在早期阶段没有提到捕获横截面。提出了一个热力学方法中子质子辐射捕获,然后广泛争论可能是他的早期帐户的基础。费米已经遇到了类似的方法,并反复使用它。

英文摘要:

When Enrico Fermi discovered slow neutrons, he accounted for their great efficiency in inducing radioactivity by merely mentioning the well-known scattering cross-section between neutrons and protons. He did not refer to capture cross-section, at that early stage. It is put forward that a thermodynamic approach to neutron-proton radiative capture then widely debated might underlie his early accounts. Fermi had already met with a similar approach, and repeatedly used it.
