CRIS is a series of topical interdisciplinary conferences held every other year in the Catania area. CRIS 2002 was devoted to cluster physics. Varied yet related subjects such as proton emission, alpha decay, exotic cluster emission, cluster structure problems in light nuclei, atomic clusters, exotic clusters of quarks such as the predicted six-quark bound state H0 and larger lumps of strange quark matter such as strange neutron stars and other astrophysical objects, were simultaneously reviewed and discussed. Topics include: clustering, exotic clustering, clusters, nuclear physics, neutron stars, strangeness, quark matter, strange matter, and cluster radioactivity.
