	Cross section can refer to: Cross section (band), a three-piece rock band from the Mornington Peninsula, Australia Cross section (geometry) Cross section (geometry) In geometry, a cross-section is the intersection of a body in 2-dimensional space with a line, or of a body in 3-dimensional space with a plane, etc.... , the intersection of a 3-dimensional body with a plane Radar cross section Radar cross section Radar cross section is a measure of how detectable an object is with a radar. When radar waves are beamed at a target, only a certain amount is reflected back.... , the unit of measure of how detectable an object is with a radar Cross section (physics) Cross section (physics) In nuclear physics and particle physics, the concept of a cross section is used to express the likelihood of interaction between particles.When particles are thrown against a foil made of a certain substance, the cross section is a hypothetical area measure around the target particles that represents a surface.... , the likelihood of an interaction event between two particles Neutron cross-section Neutron cross-section The total neutron cross-section of an isotope of a chemical element is the effective cross section area that an atom of that isotope presents to neutron scattering and neutron absorption.... Neutrino cross section Absorption cross section Absorption cross section 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.... Photoionisation cross section Photoionisation cross section *Photoionisation cross section* in the context of condensed matter physics refers to the probability of a particle being emitted from its electronic state.... Section (fiber bundle) Section (fiber bundle) In the mathematical field of topology, a section of a fiber bundle, π: E → B, over a topological space, B, is a continuous map, s : B → E, such that π=x for all x in B.... , in differential and algebraic geometry and topology, a section of a fiber bundle or sheaf Cross-sectional data Cross-sectional data Cross-sectional data in statistics and econometrics is a type of one-dimensional data set. Cross-sectional data refers to data collected by observing many subjects at the same point of time, or without regard to differences in time.... , a type of one-dimensional data set in statistics and econometrics Cross section (geology), a drawing of the geology at depth along a line of the Earth's surface.
