Cross section (physics) — A cross section is the effective area which governs the probability of some scattering or absorption event. Together with particle density and path length, it can be used to predict the total scattering probability via the Beer Lambert law. In… … Wikipedia
cross section — 1. a section made by a plane cutting anything transversely, esp. at right angles to the longest axis. 2. a piece so cut off. 3. a photograph, diagram, or other pictorial representation of such a section. 4. the act of cutting anything across. 5.… … Universalium

Neutron cross-section — The total neutron cross section of an isotope of a chemical element is the effective cross sectional area that an atom of that isotope presents to neutron scattering and absorption. cattering versus absorptionWhen a neutron approaches an atomic… … Wikipedia
Absorption cross section — is a measure for the probability of an absorption process. More generally, the term cross section is used in physics to quantify the probability of a certain particle particle interaction, e.g., scattering, photoabsorption, etc. (Note that light… … Wikipedia
Scattering cross-section — The scattering cross section, sigma; scat, relates the scattering of light or other radiation to the number of particles present. In terms of area, the total cross section ( sigma;) is the sum of the cross sections due to absorption, scattering… … Wikipedia

Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… … Wikipedia
Atomic nucleus — A figurative depiction of the helium 4 atom with the electron cloud in shades of gray. In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom … Wikipedia
