At a time when our need for electricity is growing rapidly, why are we creating a system based on intermittent wind and solar generated power? In 2025 U.S. spending on renewable energy ...

How big is a helium atom? Or maybe the better question is: How small? After an intricate game of particle jockeying, physicists have now measured the radius of the helium nucleus five times more ...

Standardizing calculations of the helium byproducts generated in advanced fission and fusion energy system materials can increase reactor safety and longevity, according to a study led by University ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...

Why does the sun shine, and how does it avoid burning out? The sun's energy is produced through a process called fusion, where four hydrogen atoms fuse to create one helium atom. With around 10^57 ...

Reaction scheme and energetic level of the investigated reaction of the helium hydride ion with deuterium. It is a swift and barrierless reaction, contrary to earlier theories. Background: The ...

For the first time, an international team of scientists has succeeded in filming quantum physical effects on a helium dimer as it breaks apart. The film shows the superposition of matter waves from ...

In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the ...
