Scientists have discovered the elusive properties hidden within promethium, a rare earth element that has remained largely ...

For the first time, scientists have revealed crucial properties of the mysterious, radioactive substance promethium — nearly eight decades after the elusive rare earth element was discovered.

The ORNL scientists bound, or chelated, radioactive promethium with special organic molecules called diglycolamide ligands. Then, using X-ray spectroscopy, they determined the properties of the ...
