This volume contains papers from the lectures and seminars given at the School. The lectures centered around a review and discussion of the most significant results obtained to date through the study of nuclear structure with electromagnetic and other high energy probes. Seminars of a more specialized nature were devoted to a discussion of recent results obtained in several research centers.

The NATO Advanced Study Institute "New Vistas in Electro-Nuclear Physics" was held in Banff, Alberta, Canada from August 22 to September 4, 1985. This volume con tains the lecture notes from that Institute. The idea to organize this Institute coincided with the award of funding for a pulse stretcher ring at the University of Saskatchewan's Linear Accelerator Laboratory. This together with the high level of interest in electron accelerators worldwide convinced us that it was an appropriate time to discuss the physics to be learned with such machines. In particular that physics which requires high energy and/or high duty cycle accelerators for its extraction was intended to be the focus of the Institute. Thus the scope of the lec tures was wide, with topics ranging from the structure of the trinucleons to quark models of nucleons, QCD, and QHD. The theme however was that we are just trying to under stand the nucleus and that the electromagnetic probe can serve as a powerful tool in such a quest.

In this important volume, major events and personalities of 20th century physics are portrayed through recollections and historiographical works of one of the most prominent figures of European science. A former student of Enrico Fermi, and a leading personality of physical research and science policy in postwar Italy, Edoardo Amaldi devoted part of his career to documenting, both as witness and as historian, some significant moments of 20th century science. The focus of the book is on the European scene, ranging from nuclear research in Rome in the 1930s to particle physics at CERN, and includes biographies of physicists such as Ettore Majorana, Bruno Touschek and Fritz Houtermans.Edoardo Amaldi (Carpaneto, 1908 - Roma, 1989) was one of the leading figures in twentieth century Italian science. He was conferred his degree in physics at Rome University in 1929 and played an active role (as a member of the team of young physicists known as ?the boys of via Panisperna?) in the fundamental research on artificial induced radioactivity and the properties of neutrons, which won the group's leader Enrico Fermi the Nobel Prize for physics in 1938. Following Fermi's departure for the United States in 1938 and the disruption of the original group, Amaldi took upon himself the task of reorganising the research in physics in the difficult situation of post-war Italy. His own research went from nuclear physics to cosmic ray physics, elementary particles and, in later years, gravitational waves. Active research was for him always coupled to a direct involvement as a statesman of science and an organiser: he was the leading figure in the establishment of INFN (National Institute for Nuclear Physics) and has played a major role, as spokesman of the Italian scientific community, in the creation of CERN, the large European laboratory for high energy physics. He also actively supported the formation of a similar trans-national joint venture in space science, which gave birth to the European Space Agency. In these and several other scientific organisations, he was often entrusted with directive responsibilities. In his later years, he developed a keen interest in the history of his discipline. This gave rise to a rich production of historiographic material, of which a significant sample is collected in this volume.

Progress in Particle and Nuclear Physics, Volume 24: The Nature of Hadrons and Nuclei by Electron Scattering covers the proceedings of the International School of Nuclear Physics. The book presents 24 papers that discuss topics concerning hadrons and nuclei. The coverage of the text includes electron scattering and few-nucleon systems; occupation probabilities of shell-model orbitals; and the response function of nuclear matter. The book also tackles the internal spin structure of the nucleon; parity-violating electron scattering; and hard pion exchange currents and the backward deuteron disintegration. The text will be of great use to scientists involved in hadron and nucleon research.
