First edition. The Discovery of Nuclear Fission. First edition, journal issues in original printed wrappers, including the true first appearance of Hahn and Strassmann's discovery of nuclear fission, as well as the work of Hahn and Meitner which led up to the discovery, and the subsequent work of Hahn and Strassmann on the identification of the fission products. "Few modern discoveries have influenced mankind so rapidly and so profoundly as has nuclear fission" (Segré, p. 42). "Early in December 1938 [Hahn and Strassmann] thought they had established some decay chains in which the genetic relations appeared to be solidly known. Supposedly four isotopes of radium were decaying to Ac[tinium] and then to Th[orium] . To make doubly sure, Hahn and Strassmann decided to identify the radium isotopes beyond any doubt. They submitted them to several stringent chemical tests using barium as a carrier and radium as a tracer.These superb experiments forced Hahn and Strassmann to conclude reluctantly that the hypothetical radium isotopes were in fact barium! In their historic 22 December paper [published 6 January 1939] for Naturwissenschaften they wrote: 'As chemists, in consequence of the experiments just described, we should change the schema given above and introduce the symbols of Ba, La, Ce in place of Ra, Ac, Th. As 'nuclear chemists,' working very close to the field of physics, we cannot yet bring ourselves to take such a drastic step, which goes against all previous experiences of nuclear physics.' A few lines earlier, however, the authors had noted 'that the sum of the mass numbers of Ba + Ma [technetium], for instance 138 + 101, gives 239'-a clear sign that they were thinking of fission. This is the moment of the discovery of nuclear fission" (Segré, p. 42). Hahn and Strassmann's paper "started scientists down the path to the atomic bomb. Originally collaborating with Lise Meitner who was forced to flee Nazi Germany in 1938, they had been working with uranium and bombarding samples with slow neutrons. They realized that this caused the uranium atoms to split into lighter nuclei releasing large amounts of energy, and the implications were not lost to a world at war" (Dibner). "Experiments conducted in 1938 at Berlin by Hahn and Strassman [sic] were reported to Lise Meitner, an Austrian scientist who had fled to Copenhagen to escape religious persecution. She and her nephew, O. R. Frisch, working in Niels Bohr's laboratory, found the true explanation of these phenomena. The interpolation of a neutron into the nucleus of a uranium atom caused it to divide into two parts and to release energy amounting to about 200,000,000 electron volts. This process bore such a close similarity to the division of a living cell that Frisch suggested the use of the term 'fission' to describe it" (PMM). Hahn received the 1944 Nobel Prize in Chemistry "for his discovery of the fission of heavy nuclei." We have been unable to trace any other comparable set of these original issues, or even just the January 6 issue, in original printed wrappers, on the market. Hahn and Strassmann's work is most often encountered in bound volumes of Die Naturwissenschaften (or extracts therefrom), or in the summary paper 'Uber das Zerplatzen des Urankernes Durch Langsame Neutronen' published in the Transactions of the Prussian Academy of Sciences 1939 (it appeared as issue No. 12 of this journal, published in the summer of 1939). Hahn and Meitner worked together at the Kaiser-Wilhelm Institute (KWI) of Chemistry in Berlin from 1912, discovering the new element protactinium in 1918; Strassmann joined them there in 1929 and Götte in 1935. When, after the First World War, limitations for women in the academic world were lifted, Meitner became professor at the KWI; Hahn became its director in 1928. "In 1934 [Enrico] Fermi roused the world of radioactivity with his method of neutron bombardment and that same year reported on the possible production of transuranic elements by irradiating uranium with neutrons. The irradiation had led to radioactive substances with different half-lives such as 10s, 40s, 13min, and 90min. Fermi's group had separated the 13-min and 90-min 'bodies' chemically from uranium and had shown that they were not isotopes of elements, which are located only a few places below uranium in the Periodic Table . they assumed that the uranium nucleus with the extra neutron transformed, via beta decay, into a nucleus of an element with the number 93 in the Periodic Table. That could still be unstable and transit, by another beta decay, into a nucleus of element 94. "The idea of more than 92 elements was, of course, contested. Ida Noddack, a renowned chemist and co-discoverer of the element rhenium, pointed out that all known elements had to be excluded before new ones were proposed. This very sound advice was not taken. Nuclear physicists saw no possibility for a nucleus to fragment into large pieces. Nothing more drastic than alpha decay had ever been observed. Another way out was also proposed: in spite of Fermi's interpretation, his 13-min body might be an isotope of protactinium, element number 91. Here Hahn and [Lisa] Meitner came in. After all, they were discoverers of protactinium and knew the properties of this element" (Brandt, pp. 264-265). "'On the Artificial Conversion of Uranium with Neutrons' [1 - see numbering of papers below], Hahn and Meitner called their first work on the uranium problem, which was published on 11 January 1935 in Naturwissenschaften. In the text it says, 'Amongst the many radioactive substances produced with neutrons uranium claims a special interest. For Fermi, Rasetti, and d'Agostino came to the conclusion from their common investigation that a radioactive element of higher atomic number than 92 was formed by the irradiation of uranium with neutrons . We now have set about a detailed investigation of this uranium process .' "It was not protoactinium. Hahn and Meitner succeeded in ascertaining that with.…

4to. 1 1/4 pp. An einen jungen Amerikaner, der sich für Naturwissenschaften interessierte.Da werden Sie sicher wissen, dass Otto Hahn und ich Chemiker waren - nicht physiker, wie oft angenommen wird. Lise Meitner war die Physikerin, die über 30 Jahre mit Otto Hahn zusammengearbeitet hatte und Deutschland im Sommer 1938 verlassen musste, weil Sie Jüdin war []Nachdem wir die Kernspaltung in Berlin entdeckt hatten, wurde Lise Meitner in Kenntnis gesetzt. Gemeinsam mit ihrem Neffen, dem Physiker Otto Robert Frisch [] hat sie unser Ergebnis mit phyiskalischen Methoden bestätigt []" - Beiliegt: Portraitphotographie ohne U., ein Druck seines Vortrags Friedliche Chemie der Atomkerne" (1948).…

First edition, offprint issue, in which Meitner as the principal author and her colleagues examine the products of neutron bombardment of uranium and their decay patterns. It is part of a long series of experimental work undertaken by the Berlin team between 1934 and 1938, which culminated in the discovery of nuclear fission. "In 1934, intrigued by Enrico Fermi's experiments indicating that transuranic elements were produced by the neutron irradiation of uranium, Meitner [1878-1968] recruited Hahn, and later Strassmann, for the investigation that resulted in the discovery of nuclear fission. Meitner was the team's leader, interpreting the data from chemistry, radiochemistry, and her own physical measurements into the context of nuclear physics" (Dictionary of Women in Science). After the Second World War broke out, Meitner (of Jewish origin) fled Germany for Stockholm. Her forced emigration "shattered her career and clouded her scientific reputation. Five months after she left Berlin, the remaining members of her team announced the splitting of the uranium nucleus, a discovery in which she should have fully shared. Although Meitner and her nephew, the physicist Otto Frisch, gave the first theoretical interpretation for the process (and named it fission), the 1944 Nobel Prize in chemistry was awarded to Hahn alone" (Dictionary of Women in Science). Meitner concluded this paper somewhat speculatively, saying that "the processes must be neutron capture by uranium-238, which leads to three isomeric nuclei of uranium-239. This result is very difficult to reconcile with current concepts of the nucleus". It was submitted for publication in May 1937, concurrent with a near-identical second paper by the team, led by Hahn as the first author and published in the Chemische Berichte. Counter to Meitner's ambiguity, Hahn interpreted the data much more decisively, stating that the "chemical distinction [of transuranes] from all previously known elements needs no further discussion". Their contrasting reports speak to the disciplinary divide - between physics and chemistry - with which the team continued to grapple. Octavo, pp. 249-70. With numerous tables and diagrams within text. Original printed wrappers, wire-stitched as issued. "Kern" ("nucleus") pencilled on front cover. Spine splitting a little at ends: a near-fine copy.…
