BEIJING, June 5 (Xinhua) -- A research team led by Chinese scientists has synthesized a new isotope protactinium-210 for the first time, which is currently the most neutron-defici ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have synthesized a new isotope—protactinium-210—for the first time. It is the ...

The modern atomic weight for the predicted element, or protactinium as it is now known, is close to 231. Even though this seems reasonably accurate, Mendeleev was somewhat unlucky regarding this ...

By comparing the experimental data of hyperfine peak wavelengths with theoretical models, Kröger was able to identify 20 new energy levels in protactinium's hyperfine structure. By expanding on ...

Protactinium turns 100. The importance of protactinium chemistry for obtaining highly attractive fissile material from thorium has been recognized since the 1940s. However, the story really begins 100 ...

As discoverers of eka-tantalum’s longest-lived isotope, Meitner and Hahn named this new element protactinium. They had isolated protactinium 231, a member of the uranium 235 decay chain. In 1938, they ...
