Coherent neutron wave propagation through a substance (Q2380194)

The propagation of neutrons through an inhomogeneous crystal medium with density fluctuations is investigated. The scattering process is described by the optical model within the framework of which the Lipman-Schwinger equation \[ \Psi=\Psi_0+G\delta U\Psi \] is considered. Here, the wave function \( \Psi \) describing neutron scattering \( \delta U \) is the perturbation caused by crystal density fluctuations and \( \Psi_0 \) is the incident wave. The optical potential allows the scattered neutron wave intensity to be calculated.
