For the first time, an international research team has succeeded in observing a two-photon decay on a so-called bare atomic nucleus from which the entire electron shell has been removed. The ...

Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...

Planning and Carrying Out Investigations: Designing experiments to measure radioactive decay and the effects of radiation. (Example: Conducting experiments to observe how distance and shielding ...

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 ...

An exotic and extremely rare nuclear decay that involves the simultaneous capture of two atomic electrons by a xenon-124 nucleus has been observed in a dark-matter detector. Physicists in the XENON ...

Two decades in the making, a new flagship facility for nuclear physics opened on May 2, and scientists from the Department of Energy's Oak Ridge National Laboratory have a hand in 10 of its first 34 ...
