In general, nuclear cross-sections can be measured for all possible interaction processes together, in this case they are called total cross-sections (σt). Periodic Table
Total Cross-section
In general, nuclear cross-sections can be measured for all possible interaction processes together, in this case they are called total cross-sections (σt). The total cross section is the sum of all the partial cross sections such as:
- elastic scattering cross-section (σs)
- inelastic scattering cross-section (σi)
- absorption cross-section (σa)
- radiative capture cross-section (σγ)
- fission cross-section (σf)
σt = σs + σi + σγ + σf + ……
The total cross-section measures the probability that an interaction of any type will occur when neutron interacts with a target.
