Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly understood. These massless particles mediate the strong nuclear force, ...

Particles racing through space at nearly the speed of light pack energy millions of times greater than anything we can create on Earth. For decades, these cosmic bullets have puzzled scientists: where ...

Helium-3 (³He) may be a rare isotope, but it can play an outsized role in environmental monitoring and radiation detection technologies.  Much recent attention has focused on high-precision ...

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 ...

Helium-3 is the lighter cousin of ordinary helium, helium-4. Its atomic nucleus has two protons and two neutrons (hence the 4 after the abbreviation for the element); in helium-3, one of the ...

Normal helium, which is 700,000 times more common than helium-3, is called helium-4 because it has two protons and two neutrons. Whereas helium-4 is a common product of the decay of radioactive ...

That is, helium which differs from normal helium, or 4 He, so called because it contains two protons and two neutrons and is continuously produced by radioactive decay.

The loose protons are a fitting stand-in for antimatter particles, ... To keep up the magnetic field suspending the protons, the superconducting magnet needs to stay cooled with liquid helium to ...
