Neutral Gas - A gas containing atoms and molecules but essentially no ions or free electrons ...
Neutral Gas and Ion Composition
The chemical composition of the gas changes with distance from the nucleus in a complex chain of chemical reactions. The 'parent molecules' at the beginning of this chain reflect the composition of the nucleus.
Neutral Gas Mass Spectrometer (ING):
This measured the elemental and isotopic compositions of the neutral gases in the coma. The instrument was comprised of two mass spectrometers.
The outer neutral gas envelope of Earth, or geocorona, consists mostly of the lightest atoms, hydrogen and helium, and continues beyond 4-5 RE, with diminishing density.
A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV); the ion beam is then passed through a neutral gas region, where the ions neutralize via charge-exchange reactions with the neutral gas.
A machine, such as an electric-arc chamber, that will generate very high heat fluxes to convert neutral gases into plasma.
2. A device which uses the interaction of a plasma and electrical field to generate a current.
The interstellar medium (ISM) comprises cold neutral gas (H I at ≈ 70 K), warm neutral gas (H I at 6,000 K) and hot ionised plasma (H II at 106 K) primarily located in the plane of the galaxy in the spiral arms.
The appearance of genuinely diffuse, space-filling neutral gas will then be as excess absorption beyond the extrapolated behavior of the narrow individual lines, or, at high enough spectral resolution, ...
The coma is comprised of water vapor, carbon dioxide gas, and other neutral gases that have sublimed (evaporated from a solid, skipping the liquid phase) from the solid nucleus.
In certain interstellar regions of cold (typically 20 K) neutral gas, densities can reach as high as 1012 particles/m3.
Gilfanov and Bogdan chose elliptical galaxies for their study because they have less neutral gas and dust to absorb the X-rays than spiral galaxies have.
coma: dense cloud of water, carbon dioxide and other neutral gases sublimed from the nucleus;
hydrogen cloud: huge (millions of km in diameter) but very sparse envelope of neutral hydrogen; ...
If the electrons constituting the current have sufficient energy (the ionization energy is different for each substance), they force other electrons out of the neutral gas molecules, ...
The oldest quasars (z 4) display a Gunn-Peterson trough and clearly have absorption regions in front of them indicating that the intergalactic medium at that time was neutral gas.
(b) At about 300,000 years after the Big Bang, the plasma of free electrons and nuclei condensed to form a neutral gas, in a process called recombination.
There is virtually no interaction with a magnetic field in a neutral gas, but in a plasma extremely close coupling with the magnetic field means that whatever the plasma is doing intimately affects the magnetic field and vice versa.
The ionosphere contains mostly neutral gases and ionized oxygen, hydrogen and helium.
The more distant parts of the orbit around Mars would have allowed instruments to probe the ions and neutral gas escaping from the Red Planet, which interact with the charged-particle "wind" blowing outward from the Sun.
Coma--A dense water cloud, made up of carbon dioxide and neutral gases, that comes off of the nucleus.
Hydrogen cloud--A huge section of hydrogen.
COMA
A coma is the roughly spherical blob of gas that surrounds the nucleus of a . The coma is comprised of water vapor, carbon dioxide gas, and other neutral gases that have from the solid nucleus. The coma and the nucleus form the head of a comet.
A plasma is an extremely hot gas that is composed of free-floating ions (atomic nuclei stripped of some electrons - making the ions positively charged) and free electrons (negatively charged). A plasma behaves much differently than a neutral gas, ...
The electron is a subatomic particle that carries a negative electric charge. It has elementary particle and is believed to be a point particle....

DLA's dominate the neutral gas content of the Universe and may be expected to constitute the primary reservoir of star-forming gas at high redshift.
The resulting atoms form neutral gases that are dispersed along Europa's orbit and is estimated to mass around 60,000 tons. The cloud is hypothesized to act as both a source and a sink of charged particles (APL press release).
where the fractional ionization is very low (one part per million or less), neutral particles only rarely encounter charged particles, and so are not well-coupled. Thus, the interstellar magnetic field can drag the ions through the neutral gas ...
