Atomic spectroscopy — is the determination of elemental composition by its electromagnetic or mass spectrum. Atomic spectroscopy is closely related to other forms of spectroscopy. It can be divided by atomization source or by the type of spectroscopy used. In the… … Wikipedia
Atomic weight — (symbol: A sub|r) is a dimensionless physical quantity, the ratio of the average mass of atoms of an element (from a given source) to 1/12 of the mass of an atom of carbon 12.cite journal | author = International Union of Pure and Applied… … Wikipedia
Atomic percent — or at.% is a measure of concentration of dopant, used in chemistry, physics of solid state lasers and spectroscopy.The meaning of this term strongly depends on the context, host material and dopant. In particular, atomic percent may refer to:(A)… … Wikipedia
Atomic stopping power — is a measure of the energy loss of a particle (usually a heavy, ionizing particle such as an alpha particle) traveling through a material. Usually expressed as MeV cm², the atomic stopping power is the energy loss of a particle per distance… … Wikipedia
Atomic force microscope — The atomic force microscope (AFM) or scanning force microscope (SFM) is a very high resolution type of scanning probe microscope, with demonstrated resolution of fractions of a nanometer, more than 1000 times better than the optical diffraction… … Wikipedia
