Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

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 ...

In Wednesday’s issue of Nature, a new paper describes a potentially useful way of measuring the interactions between normal matter and exotic particles, like antiprotons and unstable items like kaons ...

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-3 is ...

Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level 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, ...

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 ...

The Universe's first molecule is found at last! That's what the headlines have been proclaiming this week, as NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has observed a hitherto ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. There's a natural resource found beneath Earth's surface that's been ...
