Elastic and Inelastic neutrons scattering

Click For Summary
SUMMARY

This discussion focuses on the calculation of energy loss in elastic and inelastic neutron scattering, specifically under the assumption of isotropic scattering in the center of mass frame. For elastic scattering, the conservation of momentum and kinetic energy principles are applied to determine the energy lost, with the angle after collision being a critical variable. In the case of inelastic scattering, the energy lost is contingent upon the excitation of the target nuclide and the neutron's initial energy, necessitating specific data for accurate calculations.

PREREQUISITES
  • Understanding of conservation of momentum and kinetic energy principles

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.
