There Aldo Antognini's team generates so-called muonic helium-3, in which the two electrons of the helium atom are replaced by an elementary particle called a muon. This allows the nuclear radius ...

Muonic helium-3 is a special form of helium in which the atom s two electrons are replaced by a single, much heavier muon. Skip to main content. Your source for the latest research news.

In 1975, a paper was published in the prestigious journal Physical Review Letters that was co-authored by a cat. This wasn’t ...

Instead of water, they used a nanoscopic droplet of liquid helium cooled to -273°C as the solvent – and instead of a grain of salt, they used an atom of sodium.. The researchers embedded a ...

Along with 60 billion cubic feet of natural gas, about 6 billion cubic feet of helium rests safely in the Bush Dome until it’s needed for one of a host of purposes—by astronauts, party store ...

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.

Only about one helium-3 atom exists for every million helium-4 atoms, Horton said. The team measured about 10 million helium-3 atoms per gram of olivine crystals.

Helium One (LON: HE1) starts out with a rather good idea. The world's looking short of helium so why not go drill for some? Well, OK, that's a bit simple but there's good method there as well. We ...

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).

Helium-4, an isotope of helium, has a remarkably stable nucleus; it’s also an outlier on the nuclear binding energy curve, a graph that shows how tightly atomic nuclei are held together across ...
