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