In a step toward building a nuclear clock, scientists measured light emitted when a special type of thorium nucleus decayed. Skip to content Subscribe or renew today ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

GCSE; CCEA Double Award; Radioactive decay and half-life - CCEA Gamma ray. Radioactivity was first noticed by French physicist, Henri Becquerel, in 1896, when he observed that some photographic ...

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 ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for ...

JON CHASE:'Nuclear weapons, nuclear power stations 'and life-saving medical techniques, all use radioactivity. JON CHASE:'But what is it? 'Elements hold the key. JON CHASE:'Every element is ...

The result would be a radioactive decay that released two electrons but no neutrinos: a neutrinoless double-beta. Rarest of the rare. So all we have to do is look for a neutrinoless double-beta decay.

Physicists have observed a new type of radioactive decay in which a nucleus emits two protons at once. The team, led by Alfredo Galindo-Uribarri of the Oak Ridge National Laboratory in the US, ...
