But the CMB itself cannot be seen until the Universe forms neutral atoms out of its ions and electrons, which takes hundreds of thousands of years. Chris Blake and Sam Moorfield.

Thermonuclear fusion creates a hot plasma — a state of matter formed of ions and electrons rather than the electrically neutral atoms that are found in gas — that can be confined, for example ...

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

What started out as an ordinary but extremely cold gas--a bunch of neutral atoms moving around fairly freely, ... so the ions are packed closely enough to make the interaction energy enormous.

Mar. 11, 2022 — When we think of ions, we usually think of single atoms that have lost or gained some electrons, but entire molecules can also become ions. Physicists now show that cold ...

These were cooled through interactions with the ion crystal. Then, a cloud of about three million calcium atoms are reacted with the BaOCH 3 + and the desired BaOCa + appears as new ions in the ...

To top it all, this process is nearly 100% efficient at neutralizing the speeding ions and converting them to fast atoms. Accelerated neutral atoms are very important for many applications.

Technology First fully programmable quantum computer based on neutral atoms. Most quantum computers are based on superconductors or trapped ions, but an alternative approach using ordinary atoms ...

The atoms typically prefer to sit where the light field is most intense. And there’s a problem with ions: They all have an electric charge of the same sign. That means the qubits repel one another.

The experiments indicated that the original gold adatoms were in a neutral state while applying a positive voltage gave the adatoms a negative charge. “The chemical and physical properties of ions in ...

Conventional as well as compact laser-based particle acceleration schemes hinge on accelerating electric fields and are therefore ineffective for neutral atoms, which do not respond to these fields.
