The ARIS conference series was launched with the first meeting in 2011 in Leuven, Belgium as a result of merging the "International Conference on Exotic Nuclei and Atomic Masses (ENAM)" and the "International Conference on Radioactive Nuclear Beam (RNB)".
The origin of the ENAM conferences goes back to the 1950s and 1960s to 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 ENAM conference was held. Since then subsequent conferences took place in Bellaire, Michigan (1998), in Håeenlinna, Finland, (2001), in Callaway Gardens - Pine Mountain, Georgia USA (2004) and in Ryn, Poland (2008)
The first RNB conference was organized in Berkeley, U.S.A. (1989) and the series continued with events in Louvain la Neuve, Belgium (1991), East Lansing, U.S.A. (1993), Ohmiya, Japan (1996), Divonne-les-Bains, France (2000), Argonne, U.S.A. (2003), Cortina d’Ampezzo, Italy (2006) and Grand Rapids, U.S.A. (2009)
The scientific scope of the conference maintains well-received features of the 1st ARIS and previous conferences: nuclear structure, nuclear astrophysics, fundamental symmetries and interactions, nuclear reactions and responses, nuclear properties including atomic masses and fundamental constants, nuclear moments and radii, rare decay modes, and nuclei at the driplines, nuclear EOS and its implications, heaviest elements and fission, radioactive isotope production and developments of experimental devices, computational developments, applications, and other related issues.
