Statistical properties from high resolution proton resonance reactions

High resolution proton resonance measurements are of great value in the study of statistical and non-statistical effects involving compound nuclear resonances. First, these measurements provide valuable information on both global and local properties of widths and spacings. This information is a valuable supplement to that obtained from neutron experiments. Second, as Mahaux and Weidenmueller summarize: Isobaric analog resonances provide the best understood examples of doorway states. They are thus well suited for an experimental check of the theory. Third, the measurement of channel spin interference effects provide the most sensitive test yet for certain aspects of statistical theories, as well as providing examples of new types of intermediate structure. Examples are discussed
