This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A good understanding and prediction capacity of neutron scattering cross sections is crucial to many nuclear technologies, among which all kinds of reactors based on fission process. For deformed nuclei, the computation of scattering observables for the elastic channel and the first, low-lying excited states requires coupled channel calculations. Local, phenomenological optical and macroscopic transition potentials are the most commonly used in coupled channel analyses, but their accuracy outside of their fitting range remains unpredictable. Microscopic approaches are being developed in order to improve prediction power and solve the extrapolation issue. Potentials obtained microscopically are nonlocal, and recent studies have emphasized the importance of treating explicitly this nonlocality, without using a localization procedure. Our goal in the present work is to study in a quantum framework with no adjustable parameter, the impact of the nonlocality of potentials on scattering observables of nucleon-nucleus reactions. To achieve this we study neutron scattering with the Melbourne G matrix, which represents the interaction between the projectile and one nucleon of the target, and we describe the target's structure using the RPA for our first applications to 90Zr. In order to be able to study also deformed nuclei, we do our study in the coupled channel framework. The first part of this paper is dedicated to the derivation in a unique, consistent scope of coupled equations for nucleon-nucleus scattering and of the potentials obtained with the Melbourne G matrix and RPA structure input. Secondly, we describe the codes which we wrote during this Ph.D. project: MINOLOP for the computation of microscopic potentials using the Melbourne G matrix and structure inputs given in terms of a 1-body density, and ECANOL for the resolution of coupled channel equations using nonlocal potentials as input. Eventually, we present our first applications using these two codes to study pre-equilibrium emissions due to 2-phonon excitations in 90Zr.

Book Synopsis Nucleon Optical Model,the by : Peter E Hodgson
Download or read book Nucleon Optical Model,the written by Peter E Hodgson and published by World Scientific. This book was released on 1994-08-26 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nucleon optical model is widely used to calculate the elastic scattering cross-sections and polarisations for the interaction of neutrons and protons with atomic nuclei. The optical model potentials not only describe the scattering but also provide the wave functions needed to analyse a wide range of nuclear reactions. They also unify many aspects of nuclear reactions and nuclear structure. This book consists of a comprehensive introduction to the subject and a selection of papers by the author describing the optical model in detail. It contains full references to the original literature with many examples of the application of the model to the analysis of experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: A microscopic calculation of reaction cross sections for nucleon-nucleus scattering has been performed by explicitly coupling the elastic channel to all particle-hole excitations in the target and one-nucleon pickup channels. The particle-hole states may be regarded as doorway states through which the flux flows to more complicated configurations, and subsequently to long-lived compound nucleus resonances. Target excitations for {sup 40,48}Ca, 58Ni, 9°Zr and 144Sm were described in a random-phase framework using a Skyrme functional. Reaction cross sections obtained agree very well with experimental data and predictions of a state-of-the-art fitted optical potential. Couplings between inelastic states were found to be negligible, while the pickup channels contribute significantly. The effect of resonances from higher-order channels was assessed. Elastic angular distributions were also calculated within the same method, achieving good agreement with experimental data. For the first time observed absorptions are completely accounted for by explicit channel coupling, for incident energies between 10 and 70 MeV, with consistent angular distribution results.
