UNTIL recently it was generally admitted that an atom resulting from artificial disintegration should normally correspond to a stable isotope. M. and Mme. Joliot first found evidence that it is not necessarily so; in some cases the product atom may be radioactive with a measurable mean life, and go over to a stable form only after emission of a positron. 
The Discovery of Nuclear Fission - Good Solid Chemistry Got Things on the Right Track
An outline of the history of fission is given covering the period between spring 1934, when for the first time uranium was fissioned by irradiation with neutrons but the fission products were
Unexpected Discoveries, Graded Structures, and the Difference Between Acceptance and Neglect
In June 1934 the Italian physicist Enrico Fermi published a paper in Nature entitled “Possible Production of Elements of Atomic Number higher than 92” (Fermi, 1934b). In this paper Fermi reported
Radiochemical Studies and Short-Lived Fission Products
In most cases a nuclear transformation or reaction results in a definite product, or at most a few different ones. In the Chart of the Nuclides these are located in the close vicinity of the parent,

Fission of Heavy Nuclei: a New Type of Nuclear Disintegration
THE first indication that the transmutation of heavy nuclei could be effected in a laboratory experiment was obtained by Fermi in March 1934. Curie and Joliot had just discovered that shortlived
Fermi's Element 93
We have recently pointed out1 that element 93 should have, according to the Periodic Law, other properties than those displayed by Fermi's element 932, and we found, on repeating his experiments with
Some Background Information
The atomic nucleus was discovered as a consequence of a nuclear-reaction experiment and the investigation of its properties relies to a large extent upon measurements made on a variety of nuclear
First Nuclear Reactions
The discovery by Rutherford in 1919 that \(\alpha \)-particles could induce nuclear reactions and transform isotopes and elements opened up the possibility to produce new isotopes in the laboratory.
Discoveries of isotopes by fission
Of the about 3000 isotopes presently known, about 20% have been discovered in fission. The history of fission as it relates to the discovery of isotopes as well as the various reaction mechanisms
