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.
