The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear ...

How are heavy elements formed in the universe? Extremely neutron-rich atomic nuclei and their beta-decay rates play an important role in this process. Until now, it has been very difficult to ...

How long did it take our Sun to form in its stellar nursery? Scientists are now closer to an answer. They succeeded in the measurement of the bound-state beta decay of fully-ionized thallium ions at ...

Deep under an Italian mountainside, a giant detector filled with tons of liquid xenon has been looking for dark matter—particles of a mysterious substance whose effects we can see in the universe, but ...

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

An elongation versus departure from axial symmetry (triaxiality) plot showing distinctive differences in the shapes of the parent (germanium-76, “rigid”) and daughter (selenium-76, “soft”) nuclei for ...
