A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades ...

For a mere moment after the Big Bang, no neutrons or protons are thought to have existed. These neutral and positively charged particles, respectively, make up the center of all atoms today. But ...

Rumors are circulating that laboratories in China can produce gold. Here's how gold is made in labs, as we know it.

Researchers have identified rare proton emissions that reveal how the neck of a nucleus stretches and snaps, providing a new ...

A novel apparatus at the U.S. Department of Energy's (DOE) Argonne National Laboratory has made extremely precise measurements of unstable ruthenium nuclei. The measurements are a significant ...

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

Researchers at the University of Jyväskylä (Finland), in cooperation with national and international research groups, have ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

In our three-dimensional space, elementary particles neatly filter into either bosons or fermions. But in lower dimensions, that distinction gets a bit murky.

For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons. It has 11 positive charges and 11 negative charges. The mass number of an atom is its total number of ...

Researchers have uncovered how atoms subtly rearrange themselves for up to a trillionth of a second before releasing ...
