Pershan, Harvard University LOCAL COMMITTEE AT NEW YORK UNIVERSITY Professor Joseph L. Birman Mrs. H. D. Chazel Professor H. G. Hartmann Professor L. Yarmus CONFERENCE SITE Courant Institute of Mathematical Sciences Warren Weaver Hall New York University FOREWORD The International Conference on Light Scattering Spectra of Solids was held at New York University on September 3, 4, 5, 6, 1968. The Conference received financial support from the U. S. Army Research Office (Durham), The New York State Science and Technology Foundation, the U. S. Office of Naval Research, and The Graduate School of Arts and Sciences of New York University. Co-sponsoring the Conference was the International Union of Pure and Applied Physics. The initial conception for the Light Scattering Conference arose from informal discussions held by Professor Eli Burstein, Professor Marvin Silver (representing the U. S. Army Research Office) and Professor Joseph Birman, late in 1966. In early discussions a format was put forth for a meeting to be held the following year, re viewing the state of the art, and emphasizing novel developments which had 9ccurred since the 1965 International Colloquium on Scattering Spectra of Crystals held in Paris (proceedings published in Le Journal de Physique, Volume 26, November 1965). Further consideration during the Spring of 1967 suggested that, owing to the rapid expansion of theoretical and experimental work in this field, the conference should be expanded to a full International Conference on Light Scattering by Solids. This change won enthusiastic support among the active workers whose opinion was solicited. The U. S. Army Research Office (Durham) generously agreed to give financial support to the projected Conference, based on the initial plans provided by Professor Burstein, who carried most of the burden of the planning during this early stage. In December of 1967 the Planning Committee met under the Chairmanship of Professor Burstein and decided to accept the offer of New York University to be host of the Conference. At this time the membership of all working committees was also agreed upon. A policy decision was taken that the Conference would concentrate on the basic phYSics of light scattering by SOlids, rather than on "quantum optics" or "non-linear" optics - fields already covered by other conferences. Implementation of the general philosophy guiding the Conference devolved on the Conference Secretary after December 1967. He worked with the Finance Committee in allocating our resources, and with the Program Committee Chairman, Dr. John Worlock. An attempt was made to have all active workers in the field of light scattering by solids present at the Conference: this included graduate students and post-doctoral persons entering the field. Response to the call for papers was most gratifying and was reflected in the high quality of the presentations. Approximately 225 scientists participated in the Con ference and the consensus was that it was indeed productive. All sessions were plenary and there was a great deal of active discussion after the papers, as well as in the halls. All papers which were given at the Conference appear in these Pro ceedings, as well as three (A-7, B-4, G-1) by authors who were not present. No record of discussions was kept. The Conference was fortunate in having a Distinguished Guest with us: Professor Leon Brillouin. Professor Brillouin kindly prepared his remarks on the early history of Brillouin Scattering for the Proceedings and they are given in these Proceedings. Unfortunately, the rigors of travel and other pressing professional claims prevented Professor Sir. C. V. Raman from attending, but he also prepared remarks which are included in these Proceedings. On behalf of the Conference I thank the Courant Institute of Mathematical Sciences of New York University for generously permitting us to use their Auditorium for our meeting, and for a Chamber Music Concert by the Beaux-Arts String Quartet on Wednesday Evening, September 4, 1968. The Local Committee, and particularly Mrs. Helen Chazel, worked with great energy and effect, to make the participants comfortable. The success of the Light Scattering Conference held at New York Univer sity, Washington Square Center in Greenwich Village, New York City, was gratifying to all those who put time and effort into the Conference. It is our hope that these Proceedings will be a continued and productive reminder of the Conference in time to come. Joseph L.
