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.Contents: 1) The Optical Model of Elastic Scattering2) The Optical Model Analysis of Elastic Scattering and Direct Nuclear Interactions3) The Nuclear Optical Model4) International Nuclear Model Code Comparison Study of the Spherical Optical Model for Charged Particles5) The Neutron Optical Potential6) Summary of the Hamburg Conference (in Microscopic Optical Potentials)7) Nucleon Removal and Rearrangement Energies8) The Neutron Optical Model in the Actinide Region9) The Dispersive Optical Model10) Nuclear Charge DistributionsReadership: Nuclear physicists.Key Features:Discusses simple mathematical aspects of ecology, economy and sociologyCovers the applications of phase portraits in describing microcatastrophes Investigates the temperature and chemical conditions of the origin of life of climate catastrophesStudies the dynamics of market using a simple geometrical methodsUses straightforward mathematical models to assess the validity of election procedures and suggests some new voting procedures
