In theelastic scattering reaction, the conservation of momentum and kinetic energy is represented bythe equations below.Conservation of momentum (mv)Conservation of kinetic energywhere:m=mass of the neutronnm=mass of the target nucleusTv=initial neutron velocityn,iv=final neutron velocityn,fv=initial target velocityT,iv=final target velocityT,f
