Erste Ausgabe des zweiten Teils dieser berühmten Arbeit. - "Fermi bombarded several elements of increasing atomic numbers with neutrons. He hoped to find an artificial radioactivity produced by the neutrons. His first success was with fluorine..... Immediately thereafter Fermi, with the help of Amaldi, D'Agostino, Rasetti, and Segrè, carried out a systematic investigation of the behavior of elements throughout the periodic table... In uranium and thorium the investigators found several forms of activity after bombardment bud did not recognize fission. Fermi and his collaborators, having proved that no radioactive isotopes were formed between lead and uranium, put forward the natural hypothesis that the activity was due to transuranic elements. These studies... culminated in 1938 in the discovery of fission by Hahn and Fritz Strassmann" (DSB). Fermi erhält für die hier beschriebenen Entdeckungen 1938 den Nobelpreis für Physik. - Rücken sauber nachgebunden, sonst gut erhalten. - DSB 4, 576
