Manhattan Project, SegrÃ¨s Group

SegrÃ¨s Group from left to right: Emilio SegrÃ¨s, Owen Chamberlain, Gustave Linenberger, Ann Kahn, John Miskel, Milton Kahn, John Jungerman, Martin Deutsch, Unknown, Clyde Wiegand, George Farwell, Ralph Nobles, Unknown, Unknown. Emilio Gino SegrÃ¨ (February 1, 1905 - April 22, 1989) was an Italian-born, naturalized American, physicist and Nobel laureate in physics, who with Owen Chamberlain, discovered antiprotons, a sub-atomic antiparticle. Working with his graduate students and two University of California chemists, Arthur Wahl and Joseph Kennedy, SegrÃ¨ measured rates of spontaneous fission in natural uranium and plutonium in 1942 and 1943. The plutonium was made by the 60-inch Crocker medical cyclotron at the UC Radiation Laboratory by the bombardment of uranium-238 by deuterons, the ions of heavy-water (deuterium). To investigate the possibility of spontaneous fission in plutonium, Los Alamos Director J. Robert Oppenheimer invited SegrÃ¨ and his group to move to Los Alamos to continue their experiments.
