...most of the U.S. public the hydrogen bomb was still a direful novelty last week, but to scientists there was little new about it. Long before the discovery of uranium fission they had known that familiar, plentiful hydrogen could make prime nuclear fuel. They had even demonstrated on a laboratory scale some of its nuclear reactions. They could not make the process work practically, but whenever they felt discouraged, they looked up at the shining sun whose radiation, derived from hydrogen, is the vital force of the world...
...could not copy it because they had no way of approaching the temperature of the sun's interior. They found the way on July 16, 1945, when the first uranium bomb exploded at Alamogordo, N. Mex. For an instant the heart of the bomb was hot enough to make hydrogen fuse into helium. Ever since, a hydrogen bomb has been possible...
...fusion techniques. In fission bombs, a great deal of the uranium is scattered before it can react. But in a hydrogen bomb, even a small one, the ingredients packed around the uranium core could be induced to generate a large number of free neutrons. These would make more of the uranium react, thus stepping up the efficiency of the core's explosion...
...ingredient tritium (hydrogen 3) is radioactive and is excessively rare in nature, but it is not hard to make. One method is to bombard lithium 6 with neutrons in a uranium pile. The reaction yields tritium and helium, which can be separated by simple chemistry. This job could be done in the plutonium-making piles at Hanford, but probably will be done in a special pile built without difficulty for the purpose...
...lyrics by Dorothy Fields; produced by the Theatre Guild in association with Anthony Brady Farrell) can thank its stars that they are its stars. For Broadway's Nanette Fabray and the Continent's Georges Guetary, together with Singing Comedienne Pearl Bailey, have the charm and personality to make Arms and the Girl a good deal better evening than it is a show...
