+The major algorithms for inelastic scattering were described in previous
+sections. First, a scattering cosine is sampled using the algorithms in
+:ref:`sample-angle`. Then an outgoing energy is sampled using the algorithms in
+:ref:`sample-energy`. If the outgoing energy and scattering cosine were given in
+the center-of-mass system, they are transformed to laboratory coordinates using
+the algorithm described in :ref:`transform-coordinates`. Finally, the direction
+of the particle is changed also using the procedure in
+:ref:`transform-coordinates`.

+Although inelastic scattering leaves the target nucleus in an excited state, no
+secondary photons from nuclear de-excitation are tracked in OpenMC.

+weight of the outgoing neutron is multiplied by the number of secondary
+neutrons, e.g. for (n,2n), only one outgoing neutron is tracked but its weight
