Berlin--The GSI Heavy-Ion Research Center in Darmstadt, Germany, the world leader at forging new superheavy elements, last week announced that it had added yet another entry to the periodic table--element 112. A multinational team created a single radioactive nucleus of the element, the heaviest ever observed, by bombarding a lead target with billions of high-energy zinc ions. The new element's decay chain confirmed its identity and bolstered nuclear theory: As predicted, one of its decay products has a complete ``shell'' of neutrons that stabilizes it.
