The ENAM2001 Conference was held on July 2-7, 2001 at the Rantasipi Aulanko Hotel in Hameenlinna in southern Finland. The conference was organized by the Department of Physics and the Accelerator Laboratory of the University of Jyvaskyla with support from the Physics Departments of the Universities of Helsinki and Turku. This conference, Exotic Nuclei and Atomic Masses has now gained the status of a major nuclear physics serial conference. The previous conference was held in Bellaire, Michigan, USA. The conference was first held in 1967 in Lysekil, Sweden, then entitled Conference on Nuclei Far from Stability. ENAM2001 welcomed 270 participants from 34 countries, including 17 accompanying per sons. The content of the program was selected based on the advice of the International Advisory Committee. The Committee members read and considered 253 submitted abstracts in selecting oral contributions. During the conference week 76 invited and oral talks were given. The rest of the contributions were presented in dedicated poster sessions. Many thanks go to the speakers of oral and poster presentations for their enthusiasm and for the high quality of their work which demonstrated the liveliness of the field. Participation in the lectures was high and contributions from the audience were important towards the success of this conference. The organizers would like to especially thank Cary Davids of Argonne National Laboratory for his comprehensive summary talk, which is also included in these Proceedings.

The International Conference on Exotic Nuclei and Atomic Masses (ENAM) has gained the status of the premier meeting for the physics of nuclei far from stability. The selected and refereed papers presenting the main results constitute valuable proceedings that offer everyone working in this field an authoritative and comprehensive source of reference.

The proceedings of the conference on Exotic Nuclei and Atomic Masses (ENAM98) are the scientific contributions to the most recent meeting in a long series that dates back to the late 1950s. The conference is held every three years and the participants produce a complete review of the fields of exotic nuclei; atomic masses, moments and radii of nuclei; fission, synthesis of heavy elements, the role of radioactive nuclei in the cosmos, fundamental studies and use of radioactive ion beams. The proceedings provide an excellent overview and an up to date summary of recent developments in a field that is undergoing a rapid growth due to the advent of radioactive ion beams.
