Atom smashers believe that they will eventually do much better than that...
Upshot: California's atom smashers have thus far produced some 100 new isotopes* of atoms to add to the 450 previously known. Among them: two new forms of radium, and an iron isotope (atomic weight: 52) lighter than any iron ever before found. The physicists think that some of their new isotopes may be useful in medicine and research. But most of the isotopes, like the bombarded atom itself, are very unstable...
