There are two broad categories of neutron interaction:
- Scattering, where the neutron transfers some or all of its
energy to the nucleus, but remains free after the event.
- Absorption, where the neutron enters the nucleus and other
These categories can be further subdivided into the following principle
interactions, if we consider the common energy range up to 20 MeV.
Elastic scattering (n, n)
Inelastic scattering (n, n')
Radioactive capture (n, gamma)
Charge particle emission (n, p)
Fission (n, F)
(n, 2n) reactions
