Ebook: Statistical Properties of Nuclei: Proceedings of the International Conference on Statistical Properties of Nuclei, held at Albany, New York, August 23–27, 1971

An International Conference on the "Statistical Properties of Nuclei" was held from August 23 to August 27, 1971, at the State University of New York at Albany campus. The purpose of the conference was to review the current status of the experimental and theoretical aspects of resonance reaction theories, statistics of resonance parameters such as level spacings, neutron, fission, radiative and reaction widths, level densities, fluctuations in cross sections, strength functions and its relation to the optical model, intermediate structure in particle and photon induced reactions, and statistical aspects of the decay of the compound nucleus. The conference was held under the auspices of the Inter­ national Union of Pure and Applied Physics. The organization of the conference was greatly facilitated by the financial support received from the International Union of Pure and Applied Physics, The National Science Foundation and the U.S. Atomic Energy Commission and the generous use of the physical facilities and other audio-visual services provided by the State University of New York. It is with great pleasure that I thank all tbese agencies for their kind support.
