 ==Scattering==
 
In [[scattering]], a '''differential cross section''' is defined by the [[probability]] to observe a [[scattering theory|scattered particle]] in a given [[quantum state]] per [[solid angle]] unit, such as within a given [[cone (solid)|cone]] of observation, if the target is irradiated by a [[flux]] of one particle per surface unit:
 
 :<math>{d \sigma \over d \Omega}={\hbox{Scattered flux / Unit of solid angle} \over \hbox{Incident flux / Unit of surface}}</math>
