The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

However, although photons of light existed since the first second after the Big Bang, they could not yet shine across the ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium ...

Muonic helium-3 is a special form of helium in which the atom’s two electrons are replaced by a single, much heavier muon. Yesterday, the results have been published in the prestigious journal ...

1.97007 femtometer (quadrillionths of a meter): That's how unimaginably tiny the radius of the atomic nucleus of helium-3 is. This is the result of an experiment at PSI that has now been published ...

Like atomic bombs, thermonuclear bombs are also nuclear weapons, but they instead use fusion rather than fission. When two atoms are forcibly merged into one, the new combined atom has slightly ...

Apr 29, 2025 Atomic strain sensing with a silver single atom chain A silver single-atom chain demonstrates atomic-scale strain sensing and piezoresistive effects, advancing nanotechnology and ...

There are striking similarities between how elementary particles come together to form atoms, molecules and eventually ...

To do this, the team diffracted high-energy hydrogen and helium atoms through an atom-thick graphene sheet, and saw distinctive ring patterns—a tell-tale sign of diffraction.

Education News: Niels Bohr's Nobel Lecture on December 11, 1922, titled The Structure of the Atom, is one of the most significant contributions to our understanding o.

This creates helium atoms that then wreak havoc on the vacuum wall while searching for an area with low “embedding energy” (how much energy it takes for a helium atom to be absorbed).
