Prolted States Department of Commerce Technology Administration National Institute of Standards and Technology POSTER PAPERS International Conference on Atomic and Molecular Data and Their Applications (ICAMDATA 97) Wolfgang L. Wiese and Peter J. Mohr, Editors rhe National Institute of Standards and Technology was established in 1988 by Congress to "assist industry in the development of technology . needed to improve product quality, to modernize manufacturing processes, to ensure product reliability . and to facilitate rapid commercialization ... of products based on new scientific discoveries." NIST, originally founded as the National Bureau of Standards in 1901, works to strengthen U.S. industry's competitiveness; advance science and engineering; and improve public health, safety, and the environment. One of the agency's basic functions is to develop, maintain, and retain custody of the national standards of measurement, and provide the means and methods for comparing standards used in science, engineering, manufacturing, commerce, industry, and education with the standards adopted or recognized by the Federal Government. As an agency of the U.S. Commerce Department's Technology Administration, NIST conducts basic and applied research in the physical sciences and engineering, and develops measurement techniques, test methods, standards, and related services. The Institute does generic and precompetitive work on new and advanced technologies. NIST's research facilities are located at Gaithersburg, MD 20899, and at Boulder, CO 80303. Major technical operating units and their principal activities are listed below. For more information contact the Publications and Program Inquiries Desk, 301-975-3058.

Takayanagi (Japan) Foreword This Special Publication contains the poster papers presented at the first International Conference on Atomic and Molecular Data and Their Applications (ICAMDATA), which was convened at the National Institute of Standards and Technology (NIST), Gaithersburg, MD from September 29 through October 2, 1997. One hundred seventy-one registered participants from 20 countries attended the conference. In addition to the poster papers recorded here, twenty-seven invited talks were given, which are collected in a separate volume of proceedings [1]. Atomic and molecular (A+M) data are essential for the solution of a wide range of problems in diverse fields of science and technology. Major current areas of science requiring large amounts of A+M data are astrophysics, plasma physics, atmospheric physics, and basic atomic physics. Major current technology areas in which A+M data are an essential input are the plasma processing of materials, the development of lighting sources, and spectrochemistry. The enormous variety of A+M data and the diverse data needs have led to quite a fragmentation of this field, and a focal point has been missing. This conference, as well as a planned future conference series, is therefore intended to serve as such a focal point, with one of its main purposes to bring together data producers, compilers, and users in an open forum and provide close interactions and intensive exchanges of ideas. The principal topics of the poster presentations were (a) the production of collision and radiation data, both atomic and molecular, including benchmark data; (b) the presentation and detailed description of available atomic and molecular databases, their management and data assessment, and (c) reviews of data needs in various user communities.
