Rabi, carrying these studies further, found the molecular beam much more helpful in studying the structure of an atom than an atom-smashing machine, whose use he likens to studying the Taj Mahal by dynamiting it and considering the fragments. By his method, Rabi learned, for example, that the deuteron, the simplest known nucleus, revolves like a football spinning end over...
...Bethe figured out that the shape of the deuteron (nucleus of the heavy hydrogen atom) should not be spherical but oval like a football-which agreed with the experimental findings of Professor Isidor Isaac Rabi & associates at Columbia. Year ago Dr. Bethe was hailed by astrophysicists for figuring out that carbon must be the stuff that enables the sun to turn fragments of hydrogen atoms into sunshine (TIME, Feb. 27). Lately he has been working on the function in the atom's nucleus of a particle called the "mesotron," which weighs about 200 times as much as an electron...
