Figure 16 Elastic Scattering
Figure 16 illustrates the process of elastic scattering of a neutron off a target nucleus. In the
elastic scattering reaction, the conservation of momentum and kinetic energy is represented by
the equations below.
Conservation of momentum (mv)
Conservation of kinetic energy

m
=
mass of the neutron
n
m
=
