Researchers have taken atomic diffraction to a new level, revealing surprising behaviors in high-energy helium and hydrogen ...

Helium is notoriously hard to contain because, like hydrogen, it is a tiny little atom even by atomic standards. It also expands about 750 times when it turns into a gas, according to the post’s ...

In these neutron-rich environments, atomic nuclei essentially capture neutrons before ... which occur when a radioactive isotope fuses with a helium nucleus and spits out a neutron. “These reactions ...

This phase, theoretically predicted in 1972, had only been observed in helium and ultracold atomic gases until now, and never in molecules. The work could give scientists a better understanding of ...

In a landmark achievement for fusion energy, ITER has completed all components for the world's largest, most powerful pulsed superconducting electromagnet system. A research team from the Hefei ...

Astronomers have long estimated the amount of Helium in Sun-like stars based on indirect methods, like studying hotter stars ...

For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass, it seemed that something besides the protons in the nucleus ...

This limitation has led to long-standing assumptions and uncertainties regarding the precise ratio of Helium to Hydrogen (He/H) in the Sun's surface layer.

For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass, it seemed that something besides the protons in the nucleus ...
