The conference can trace its origins to the 1950s and 1960s with the Atomic Mass and Fundamental Constants (AMCO) and the Nuclei Far From Stability (NFFS) series of conferences. Held jointly in 1992, the conferences officially merged in 1995 in Arles, France where the First International Conference on Exotic Nuclei and Atomic Masses was held. Since this beginning, subsequent conferences have been held at Bellaire, Michigan (1998) and Hämeenlinna, Finland (2001). The Fourth Conference will be at Callaway Gardens in Pine Mountain, Georgia USA and is organized by the Physics Division at Oak Ridge National Laboratory.

The conference will cover a broad list of topics including consist of a series of invited talks highlighting recent research in the following fields:

• Fundamental constants, atomic masses, and nuclear moments and radii
• Forms of radioactivity
• Nuclear structure, nuclei at the drip lines, cluster phenomena
• Reactions with radioactive ion beams
• Nuclear astrophysics
• Fundamental symmetries and interactions
• Heaviest elements and fission
• Radioactive ion beam production and experimental developments
• Applications of exotic nuclei

In addition to invited talks, contributions highlighting recent research will be solicited and several of these will be selected for oral presentations. The remaining contributions, if suitable for this conference, may be presented by a poster. The conference has always received many more abstracts than can be scheduled for oral presentations, so the poster session is expected to be quite large and we anticipate that it might extend over several evenings. The Call for Abstracts will be issued in early 2004.

Proceedings of ENAM04 will be published and will have specific guidelines as to format and length. Details will be provided closer to the time of the Conference.
