Quantum Elastic Scattering on Fixed Target

Additionally, there is assumed that during the scattering process neither modification of the inner structure of the system investigated nor other binding phenomena are produced. The measured quantity is the so-called effective crossing section Act, usually defined by the number of particle

Alternatively, it may be expressed with the help of quantum probability of detection the emergent particles coming on detector through scattering from the incident ones on target,, respecting the incident flux of particle on target 

Worth noting that this picture is valid as far the time of interaction is significantly less than the time of preparation (of incident flux) or of the time
