This book deals with a particular phase in the early history of nuclear physics: what in effect became a race between four laboratory teams to be the first to achieve the transmutation of atomic nuclei with artificially accelerated nuclear projectiles (protons) in high-voltage discharge tubes. The laboratories and their team leaders were as follows: John D. Cockcroft at the Cavendish Laboratory in Cambridge, England; Ernest O. Lawrence at the Radiation Laboratory in Berkeley, California; Merle A. Tuve in the Carnegie Institution of Washington; and Charles C. Lauritsen at the Kellogg Radiation Laboratory in Pasadena, California. The 'race' was won by the English team in 1932; however, the details of the race are less well known. This volume covers the background for the development of particle accelerators in the 1920s, the growth of the laboratories and their teams, the race itself and its aftermath. It also covers the reaction of the different laboratories to the discovery of nuclear fission, their wartime roles, and a brief epilogue on the later careers of the principal personalities. This book also provides an overview of the history of nuclear physics, from Rutherford's nuclear atom of 1911 to nuclear fission on the eve of World War II.

Here the development of nuclear weapons is viewed from the perspective of the scientist. From the discovery of fission to the Manhattan Project, to Hiroshima and Nagasaki, the arms race and early steps toward arms control, this book provides a context for developments in the period 1939-1963. It discusses the scientists' technical contributions, the novelty of working for the government on a secret project, political lobbying, the private anguish over the morality of creating weapons of mass destruction while being subject to public adoration as the wizards who produced the bomb, and finally the rapid descent for some into the shattering category of security risk during the McCarthy period. Lawrence Badash traces the course of this tumultuous and apocalyptic period with scientific clarity and sympathetic understanding.

A history of the origins and development of the American atomic bomb program during WWII. Begins with the scientific developments of the pre-war years. Details the role of the U.S. government in conducting a secret, nationwide enterprise that took science from the laboratory and into combat with an entirely new type of weapon. Concludes with a discussion of the immediate postwar period, the debate over the Atomic Energy Act of 1946, and the founding of the Atomic Energy Commission. Chapters: the Einstein letter; physics background, 1919-1939; early government support; the atomic bomb and American strategy; and the Manhattan district in peacetime. Illustrated.

In this absorbing account of life with the great atomic scientist Enrico Fermi, Laura Fermi tells the story of their emigration to the United States in the 1930s—part of the widespread movement of scientists from Europe to the New World that was so important to the development of the first atomic bomb. Combining intellectual biography and social history, Laura Fermi traces her husband's career from his childhood, when he taught himself physics, through his rise in the Italian university system concurrent with the rise of fascism, to his receipt of the Nobel Prize, which offered a perfect opportunity to flee the country without arousing official suspicion, and his odyssey to the United States.

and less as the emanation unden\'ent radioactive decay, and it became motion less after about 30 seconds. Since this process was occurring very rapidly, Hahn and Sackur marked the position of the pointer on a scale with pencil marks. As a timing device they used a metronome that beat out intervals of approximately 1. 3 seconds. This simple method enabled them to determine that the half-life of the emanations of actinium and emanium were the same. Although Giesel's measurements had been more precise than Debierne's, the name of actinium was retained since Debierne had made the discovery first. Hahn now returned to his sample of barium chloride. He soon conjectured that the radium-enriched preparations must harbor another radioactive sub stance. The liquids resulting from fractional crystallization, which were sup posed to contain radium only, produced two kinds of emanation. One was the long-lived emanation of radium, the other had a short life similar to the emanation produced by thorium. Hahn tried to separate this substance by adding some iron to the solutions that should have been free of radium, but to no avail. Later the reason for his failure became apparent. The element that emitted the thorium emanation was constantly replenished by the ele ment believed to be radium. Hahn succeeded in enriching a preparation until it was more than 100,000 times as intensive in its radiation as the same quantity of thorium.
