Atoms can be more overweight than we thought, a team of scientists in the United States has discovered. They have sent atoms crashing into one another in a particle accelerator to create bloated ...

The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements Scientists ...

Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

Neutrons shouldn’t be all that mysterious. Found inside every atomic nucleus, they may seem downright mundane—but they have long confounded physicists who try to measure how long these particles can ...

I. CURIE, Joliot and Preiswerk 1 have shown that by bombarding silicon and phosphorus by neutrons there are produced radio-elements which spontaneously emit neutrons, in addition to electrons (Fermi ...
