The phrase "atomic number density" is correct and usable in written English.
It can be used in scientific contexts, particularly in physics or chemistry, to describe the number of atoms per unit volume in a given substance.
Example: "The atomic number density of the material was calculated to determine its properties under various conditions."
Alternatives: "atom density" or "number density of atoms".
where eta and dS denote the atomic number density, i.e., number of carbon atoms per unit area and the surface area element of the graphene sheet, respectively.
We model electronic stopping by a velocity-proportional friction force F=n k v, where n is the atomic number density of Au and v is the atom velocity.
Laser-induced fluorescence (LIF) and pyrometry determined relative titanium gas phase atomic number density and deposition temperature, respectively.
The thermophoresis causes a global atomic number density increase towards the cold region of the domain.
Consequently, the effect of atomic oxygen number density abundance on 844.6 nm dayglow emission is further studied by treating the atomic oxygen number density as a variable parameter in the present model.
Due to its high atomic number, high density and wide band-gap energy, lead iodide is a promising nuclear-radiation detector material.
In addition, there is a variable degree of attenuation of the signal, depending on the thickness, atomic number and density of superimposed materials, that has to be taken into account while interpreting the chemical maps.
The probability of plural or multiple scattering increases in proportion to the specimen thickness and rising atomic number or density.
Photon interactions with tissue, such as photo-electric absorption, Compton scatter, and pair production, are dependent on the atomic number, electron density of the tissue, and photon energy.
The value of θc is dependent both upon the X-ray energy and upon the atomic number and density of the material used for the reflective optics.
The model predicts a positive correlation between the zenith intensity of 844.6 nm dayglow emission and atomic oxygen number density.
