...most of the protons missed their targets, the hydrogen-lithium reaction gave a net loss of energy, and no one knew how to improve its efficiency. Other reactions of light elements yielded theoretical energy too, but all of them were overshadowed by the wartime development of atom-splitting uranium fission...
...under the Atomic Energy Commission, which is pushing similar work with beams of nitrogen and other large nuclei in many parts of the U.S. The AEC's long-range interest can be guessed at. When a nitrogen atom can be made to hit U-238, not normally considered fissionable, it almost always causes fission. When it forms Element 99, it liberates five free neutrons, and these are capable of causing fission too. AEC may be feeling for a new method of releasing atomic energy from difficult...
...willing to talk it over. Dulles suggested a preliminary exchange of views in Washington, and last week the Kremlin agreed. Two days later, the Atomic Energy Commission announced that this month "men and materials will begin moving to the Pacific proving grounds [for] weapons tests of all categories," i.e., fission and thermonuclear...
...Lewis Strauss, Joe I meant just one thing: the U.S. must get to work, on a "crash" basis, on building the "super." The super's vast explosive potentialities were based not on splitting atoms (as with the fission, or A-bomb), but in fusing atoms of one element to form another (e.g., hydrogen into helium) through in tense heat. AEC Physicist Edward Teller figured out in 1945 that a superbomb was theoretically possible. In 1947 he came within one step of working out the theoretical mechanics (at a seminar in Los Alamos attended by Dr. Klaus Fuchs...
...steel like paper. The planes themselves are approaching speeds at which aluminum aircraft skins would lose their strength, then melt. Nor is heat the only problem. Building of the first atomic reactors disclosed the fact that most metals absorb or "eat up" the atomic neutrons needed to provide the fission and motive power...
