The papers included in this volume were presented at the symposium on "Americium and Curium Chemistry and Technology" at the International Chemical Congress of Pacific Basin Societies in Honolulu, Hawaii, December 16-21, 1984. This symposium commemorated forty years of research on americium and curium. Accordingly, the papers included in this volume begin with historical perspectives on the discovery of americium and curium and the early characterization of their chemical properties, and then cover a wide range of subjects, such as thermodynamic properties, electronic structure, nuclear reactions, analytic chemistry, high pressure phase transitions, and technological aspects. Thus, this volume is a review of the chemistry of americium and curium, and provides a perspective on the current research on these elements forty years after their discovery. The editors would like to thank the participants in this symposium for their contributions. It is a pleasure to acknowledge the assistance of Ms. Barbara Moriguchi in handling the administrative aspects of the symposium and of the production of this volume. April 2, 1985 Norman M.
