This is the eighth volume of a continuing series intended to provide a forum for publication of develop­ ments in Mossbauer effect methodology and in spectroscopy and its applications. Mossbauer Effect Methodology, Volume 8, records the proceedings of the Eighth Symposium on Mossbauer Effect Methodology. The symposium was sponsored by the New England Nuclear Corporation, with emphasis on application and some attention to spectroscopy and methodology. The Symposium was held in the Mercury Ballroom of the New York Hilton on January 28, 1973. Dr. J. J. Zuckerman presided over the afternoon and evening sessions. Almost two hundred participants attended, despite the pressures of travel budget limitations, indicating a continuing high level of interest in the field. Contri­ buting Sponsors were Austin Science Associates, Elron, Nuclear Science Instruments and Ranger Electronics. The MOssbauer equipment demonstrated by these organizations continued to evolve and improve year by year, and was well received by symposium participants. A one-year break in the symposium series resulted in submission of a very large number of papers. A Selection Committee was formed and selected 16 papers for inclusion in the symposium. Regrettably, many worthwhile papers could not be included. Applications were stressed.
