Scientists have created six new isotopes of the superheavy elements, reaching in an unbroken chain of decays from element 114 down to rutherfordium. The discovery is a major step toward understanding ...

Ensuring a reliable domestic supply of critical isotopes is essential to advancing U.S. leadership in medicine, national ...

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

Researchers at the University of Waterloo have produced experimental evidence that quantum-level effects can alter the ...

Chemists searching for the island of stability now have a better map. Thanks to the discovery of six new variations of the superheavy elements on the bottom rung of the periodic table, scientists are ...

The chart of nuclides sorts isotopes by their proton vs. neutron numbers. This region shows newly discovered isotopes (yellow) that were produced at the Facility for Rare Isotope Beams by fragmenting ...

Two isotopes of a new element with atomic number Z=117 were created by an international collaboration in the reaction between unique radioactive 249 Bk target material produced at ORNL through the DOE ...

Berkeley, CA—A team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has detected six isotopes, never seen before, of the superheavy elements 104 through 114.
