Some atoms are stable, while others seem to fall apart. Lead-208 will probably last forever, while the synthetic isotope technetium-99 exists for just hours. The difference lies in the structure of ...

For decades, nuclear physicists believed that "Islands of Inversion"—regions where the normal rules of nuclear structure suddenly break down—were found mostly in neutron-rich isotopes. In these ...

The red ball, blue star and black square represent the corresponding results of Rn, Ra and Th isotopes, respectively. In the shell model, the neutron number N=126 is regarded as a neutron magic number ...

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? Researchers report on experiments to come closer to an answer. They gained insight ...

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? An international research team reports on experiments performed at the GSI/FAIR ...
