Complete set of the first offprints in the original wrappers of these 3 „fundamental papers on nuclear fission which eventually lead to the creation of the atomic bomb.“ (Dibner)
Contents, Edition: The German radio and nuclear chemists Otto Hahn and Fritz Straßmann "bombarding uranium with neutrons (as indicated by Fermi in the mid-1930s), found that treating the bombarded uranium with barium resulted in some strongly radioactive material. By late 1938 they suspected that uranium fission had occurred.“ These epochal findings had been presented by Hahn and Straßmann to the Prussian Academy on May 25th 1939. Their paper indicates in detail „fission of the uranium nucleus into two parts of about equal size with the release of much energy.“
The publication date for the present first offprint is stated „18th Sept. 1939“ in the colophon (p. 2). Known are also offprint issues with original publisher’s wrappers on green stock lacking the quotation „Einzelausgabe“ (separate edition).
Alongside the arforementioned an Austrian woman scientist of Jewish descent, Lise Meitner, colleague at the Berlin Kaiser-Wilhelm-Institute of Chemistry for decades, also contributed heavily to their findings. Meitner had to flee Nazi Germany in 1938 but continued her research in exile, e.g. in Copenhagen, where she worked in the laboratory of Niels Bohr.
Through Bohr and Fermi this nuclear energy was to become a reality in the atomic pile and the bomb blasts of 1945 as well as in the nuclear power stations of the following decades. Hahn received the Nobel Prize for Chemistry in 1944, and together with Meitner and Strassmann, the Fermi award in 1966.“ (All quotes Dibner). If the 1st paper from 1939 contains the first comprehensive description of this core nuclear achievement, the following to corresponding papers published by Hahn and Straßmann with support by chemist Hans Götte during the Second World War in 1942 and 1944 describe experiments to identify the fission fragments.
Condition: Very good, papers 1 and 3 with one small tear on bottom of spine, paper 3 with one very little chip on front cover at top of spine.
