Elastic and Inelastic neutrons scattering

    Elastic and Inelastic neutrons scattering..!!

    How I can find the energy lost by the neutron in elastic scattering and inelastic scattering, if we assumed its isotropic scattering in the center of mass?

    If its elastic, then conservation of momentum and kinetic energy will give you the result. There is one degree of freedom - the angle after collision.

    For inelastic scattering you need the amount of kinetic energy lost to exciting the target. That is a function of the nuclide and the neutron energy - there is information available.
