High-Energy Physics and Nuclear Structure : Proceedings of the Third International Conference on High Energy Physics and Nuclear Structure sponsored by the International Union of Pure and Applied Physics, held at Columbia University, New York City, September 8-12, 1969

In preparing the program for this Conference, the third in the series, it soon became evident that it was not possible to in­ clude in a conference of reasonable duration all the topics that might be subsumed under the broad title, "High Energy Physics and Nuclear Structure. " From their initiation, in 1963, it has been as much the aim of these Conferences to provide some bridges between the steadily separating domains of particle and nuclear physics, as to explore thoroughly the borderline territory between the two -­ the sort of no-man's-land that lies unclaimed, or claimed by both sides. The past few years have witnessed the rapid development of many new routes connecting the two major areas of 'elementary par­ ticles' and 'nuclear structure', and these now spread over a great expanse of physics, logically perhaps including the whole of both subjects. (As recently as 1954, an International Conference on 'Nuclear and Meson Physics' did, in fact, embrace both fields!) Since it is not now possible to traverse, in one Conference, this whole network of connections, still less to explore the entire ter­ ritory it covers, the choice of topics has to be in some degree arbitrary. It is hoped that ours has served the purpose of fairly exemplifying many areas where physicists, normally separated by their diverse interests, can find interesting and important topics which bring them together.
