In a particle ejection reaction, what may or may not exist after a new particle is ejected?

The original nucleus is always left in an excited state.

The remaining nucleus may or may not exist in an excited state.

The incident neutron always leaves the nucleus.

5 / 10

What is the net effect of a neutron scattering reaction?
