The helium atoms are then ionized by the absorption of a single ultraviolet photon, the energy of which is tuned such that it is only just enough to ionize the helium – 99.9% of the photon’s energy is ...

Absolutely bonkers experiment measures antiproton orbiting helium ion It's a potentially useful technique—and it's surprising that it works. John Timmer – Mar 16, 2022 12:00 pm | 70 ...

The current results from muonic helium-3 fit well with those from previous experiments in which other methods were used. However, the PSI team's measurements are around 15 times more precise.

Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up.

KidsPost Helium isn’t just for balloons. It’s a valuable technology resource. The element -- which is rare on Earth -- is used in rockets, smartphones and medical equipment.

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 ...

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

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

Helium is used to pressurize fuel tanks, ensuring fuel flows to the rocket's engines without interruption; and for cooling systems. As fuel and oxidiser are burned in the rocket's engines, ...

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.
