We analyze the influence of Enrico Fermi’s theory of beta decay, which he formulated in December 1933, on his experimental discovery of neutron-induced artificial radioactivity four months later, in March 1934.We discuss Gian Carlo Wick’s application of Fermi’s theory in interpreting Frédéric Joliot and Irène Curie’s discovery of alpha-particle-induced artificial radioactivity, and how Fermi was then influenced by his theory in planning his neutron-bombardment experiments, in his decision to… 
Enrico Fermi’s Discovery of Neutron-Induced Artificial Radioactivity: A Case of “Emanation” from “Divine Providence”
We reconstruct Enrico Fermi’s remarkable discovery of neutron-induced radioactivity in March 1934 with a focus on the experimental apparatus he used, such as the original neutron sources preserved in
The Discovery of Artificial Radioactivity
We reconstruct Frédéric Joliot and Irène Curie’s discovery of artificial radioactivity in January 1934 based in part on documents preserved in the Joliot–Curie Archives in Paris, France. We argue
International Scientific Cooperation During the 1930s. Bruno Rossi and the Development of the Status of Cosmic Rays into a Branch of Physics
TLDR
A glimpse of the intersection between national and international dimensions during the 1930s is provided, at a time when the study of cosmic rays was still very much in its infancy, strongly interlaced with nuclear physics, and full of uncertain, contradictory, and puzzling results.

The purpose of this study, mainly historical and pedagogical, is to investigate the physical-mathematical similitudes of the spectroscopic and beta decay Fermi theories. Both theories were formulated
When Energy Conservation Seems to Fail: The Prediction of the Neutrino
A historical case study concerning the serious doubts that arose in early 1930s about the validity of the law of energy conservation in nuclear disintegrations, and the hypothesis of neutrino, will
A Short History of Nuclear Physics to the Mid-1930s
Until the late 1930s, the study of radioactivity and nuclear physics were relatively low-profile academic research fields whose applications were limited primarily to medical treatments such as
Enrico Fermi and Ettore Majorana: So Strong, So Different
By exploiting primary sources we will analyze some of the aspects of the very complex relationship between Enrico Fermi and Ettore Majorana, from 1927 (first contacts of Majorana with the Institute

Abstract.We reconstruct and analyze the path leading from James Chadwick’s discovery of the neutron in February 1932 through Frédéric Joliot and Irène Curie’s discovery of artificial radioactivity in
Enrico Fermi’s Discovery of Neutron-Induced Artificial Radioactivity:The Recovery of His First Laboratory Notebook
Abstract.We give a short description of the discovery of the first experimental notebook of Enrico Fermi (1901-1954) on his researches during March and April of 1934 on neutron-induced artificial
Neutron physics in the early 1930s
ABSTRACT: Dawning neutron physics was more complex than one might expect. The chance that the neutron comprised a proton and an electron was diffusely taken into account after the discovery of the
Artificial Radioactivity Produced by Neutron Bombardment
We describe in this paper some further results on artificial radioactivity induced by neutron bombardment, which have been obtained in the physical Laboratory of the University of Rome, after the
The Nuclear Electron Hypothesis
James Chadwick’s discovery of the neutron in 1932 is justifiably viewed as a watershed in the history of nuclear physics.1 It opened the way to all modern neutron-proton theories of nuclear structure
Artificial Radioactivity Produced by Deuton Bombardment
Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most
A ‘Nuclear Photo-effect’: Disintegration of the Diplon by γ-Rays
BY analogy with the excitation and ionisation of atoms by light, one might expect that any complex nucleus should be excited or ‘ionised’, that is, disintegrated, by y-rays of suitable energy.
The Average Energy of Disintegration of Radium E
The problem of the velocity of the particles emitted from the nuclei of dis integrating radioactive atoms has always attracted considerable attention. It was early established that in the case of the
Production of Induced Radioactivity by High Velocity Protons
CURIE and Joliot1 have reported that a number of new radioactive isotopes can be produced by the bombardment of various elements with α-particles, these isotopes emitting positive electrons. In
Artificial Production of a New Kind of Radio-Element
TLDR
The latest experiments have shown a very striking fact: when an aluminium foil is irradiated on a polonium preparation, the emission of positrons does not cease immediately, when the active preparation is removed, as for an ordinary radio-element.
