Elastic and inelastic scattering of neutrons on 238U nucleus

Advanced modelling of neutron induced reactions on 238U nucleus is aimed at improving our knowledge of the neutron scattering. Capture and fission channels are well constrained by available experimental data and neutron standard evaluation. A focus of this contribution is on elastic and inelastic scattering cross sections. The employed nuclear reaction model includes – a new rotational-vibratio...

Bulk effects in the coherent inelastic scattering of ultracold neutrons

With the use of theory developed earlier, bulk effects in ultracold neutron coherent inelastic scattering are considered both for solid and liquid target samples related to energy and momentum exchange with phonon and diffusion-like modes. For the neutron in a material trap, differential and integral probabilities for the energy transfer per bounce are presented in a simple analytic form which ...

On the scattering of fast neutrons by protons.

1. Introduction. Recent experiments by Amaldi arid his collaborators on the scattering of high-energy neutrons (of 10—15MeV.) by protons (2) have disclosed a considerable anisotropy in the angular distribution of the scattered particles. Theoretical discussions of this problem show an interesting feature in that the results depend sensitively on the basic assumptions involved with regard to the...

Quasi-elastic Scattering of Neutrons

In solids random motions of atoms may take place in connection with disorder; for instance diffusion of interstitials in solid solutions or orientation fluctuations in molecular solids. Experimentally these motions are observed mostly by resonance and relaxation techni­ ques, by optical spectroscopy and, recently, by neutron spectroscopy. In comparison to the other me­ thods neutron spectroscop...
