neutral atom

neutral atom

[′nü·trəl ′ad·əm]
(atomic physics)
An atom in which the number of electrons that surround the nucleus is equal to the number of protons in the nucleus, so that there is no net electric charge.

Scientists will look at different ways of designing the matter-light interaction used to produce entangled photons, including neutral atom memories with electronically excited interactions, nitrogen-vacancy defects in diamonds and charged quantum dots.
In a neutral atom, the number of protons and the number of electrons (negatively charged particles) are equal.
Whereas an ion gun radiates an argon ion beam, an FAB gun radiates a neutral atom beam of argon.
During its science investigation, IBEX will use a pair of energetic neutral atom "cameras" to image interactions between the million mile-per-hour solar wind continually blown out by the Sun and the low-density material between the stars, known as the interstellar medium -- interactions never before imaged.
However, Professor Gerhard Rempe and a team of physicists at the Max Planck Institute of Quantum Optics, Munich, Germany, have built a single-photon server based on a single trapped neutral atom.
Scientists at NIST have demonstrated a novel source of atom flux that can provide one, and only one, atom essentially whenever it is needed--the first time such control over neutral atom delivery has been achieved.
Beta radiation is produced whenever ionizing radiation converts a neutral atom to an ionized atom by causing the atom to lose an electron.
Once Moseley had advanced his notion of atomic numbers (see 1914), it was understood that the neutral atom contained as many electrons in its outskirts as the value of the atomic number.
IBEX is using energetic neutral atom (ENA) imaging to create the first global maps of interactions between the million mile-per-hour solar wind blown out in all directions by the Sun and the low-density material between the stars, known as the interstellar medium.
The researchers calculated that the roaming electron of the excited atom would hover around the neutral atom and form an electron cloud that resembled, of all things, an ancient trilobite.
