An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has been getting bigger since the Big Bang. When the hydrogen and helium atoms ...

With market sentiment turning bullish again and Layer 1s and utility tokens surging in adoption, this week presents a prime ...

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 journal Science .

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 ...

A method for constrained optimisation of the design of a scanning helium microscope. Bergin M, Ward DJ, Ellis J, Jardine AP. Ultramicroscopy. 2019 Dec;207:112833. doi: 10.1016/j.ultramic.2019.112833.

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).

The innovative idea from the three researchers involved proposing a different view of the excited nucleus: instead of seeing it as a closed quantum system, the trio of researchers preferred to ...
