For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...

For half a century, our view of the world has been based on the standard model of particle physics. However, this view has been challenged by theories 1 that can overcome some of the limitations of ...

Researchers from KDK Collaboration at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory recently made the first direct observations of rare decay processes, such as K-40 ...
